Some context: The Who are an English rock band that formed in 1964. Their classic line-up consisted of lead singer Roger Daltrey, guitarist and singer Pete Townshend, bass guitarist John Entwistle, and drummer Keith Moon. They are considered one of the most influential rock bands of the 20th century, selling over 100 million records worldwide and holding a reputation for their live shows and studio work. The Who developed from an earlier group, the Detours, and established themselves as part of the pop art and mod movements, featuring auto-destructive art by destroying guitars and drums on stage.
The founding members of the Who, Roger Daltrey, Pete Townshend and John Entwistle, grew up in Acton, London and went to Acton County Grammar School. Townshend's father, Cliff, played saxophone and his mother, Betty, had sung in the entertainment division of the Royal Air Force during World War II, and both supported their son's interest in rock and roll. Townshend and Entwistle became friends in their second year of Acton County, and formed a trad jazz group; Entwistle also played French horn in the Middlesex Schools' Symphony Orchestra. Both were interested in rock, and Townshend particularly admired Cliff Richard's debut single, "Move It". Entwistle moved to guitar, but struggled with it due to his large fingers, and moved to bass on hearing the guitar work of Duane Eddy. He was unable to afford a bass and built one at home. After Acton County, Townshend attended Ealing Art College, a move he later described as profoundly influential on the course of the Who.  Daltrey, who was in the year above, had moved to Acton from Shepherd's Bush, a more working-class area. He had trouble fitting in at the school, and discovered gangs and rock and roll. He was expelled at 15 and found work on a building site. In 1959 he started the Detours, the band that was to evolve into the Who. The band played professional gigs, such as corporate and wedding functions, and Daltrey kept a close eye on the finances as well as the music.  Daltrey spotted Entwistle by chance on the street carrying a bass and recruited him into the Detours. In mid-1961, Entwistle suggested Townshend as a guitarist, Daltrey on lead guitar, Entwistle on bass, Harry Wilson on drums, and Colin Dawson on vocals. The band played instrumentals by the Shadows and the Ventures, and a variety of pop and trad jazz covers. Daltrey was considered the leader and, according to Townshend, "ran things the way he wanted them". Wilson was fired in mid-1962 and replaced by Doug Sandom, though he was older than the rest of the band, married, and a more proficient musician, having been playing semi-professionally for two years.  Dawson left after frequently arguing with Daltrey and after being briefly replaced by Gabby Connolly, Daltrey moved to lead vocals. Townshend, with Entwistle's encouragement, became the sole guitarist. Through Townshend's mother, the group obtained a management contract with local promoter Robert Druce, who started booking the band as a support act. The Detours were influenced by the bands they supported, including Screaming Lord Sutch, Cliff Bennett and the Rebel Rousers, Shane Fenton and the Fentones, and Johnny Kidd and the Pirates. The Detours were particularly interested in the Pirates as they also only had one guitarist, Mick Green, who inspired Townshend to combine rhythm and lead guitar in his style. Entwistle's bass became more of a lead instrument, playing melodies. In February 1964, the Detours became aware of the group Johnny Devlin and the Detours and changed their name. Townshend and his roommate Richard Barnes spent a night considering names, focusing on a theme of joke announcements, including "No One" and "the Group". Townshend preferred "the Hair", and Barnes liked "the Who" because it "had a pop punch". Daltrey chose "the Who" the next morning.

Some context: Donald Christopher Barber (born 17 April 1930) is an English jazz musician, best known as a bandleader and trombonist. As well as scoring a UK top twenty trad jazz hit, he helped the careers of many musicians, notably the blues singer Ottilie Patterson, who was at one time his wife, and vocalist/banjoist Lonnie Donegan, whose appearances with Barber triggered the skiffle craze of the mid-1950s and who had his first transatlantic hit, "Rock Island Line", while with Chris Barber's band. His providing an audience for Donegan and, later, Alexis Korner makes Barber a significant figure in the British rhythm and blues and "beat boom" of the 1960s.
Barber and Monty Sunshine (clarinet) formed a band in 1953, calling it Ken Colyer's Jazzmen to capitalise on their trumpeter's recent escapades in New Orleans: the group also included Donegan, Jim Bray (bass), Ron Bowden (drums) and Barber on trombone. The band played Dixieland jazz, and later ragtime, swing, blues and R&B. Pat Halcox took over on trumpet in 1954 when Colyer moved on after musical differences and the band became "The Chris Barber Band".  In April 1953 the band made its debut in Copenhagen, Denmark. There Chris Albertson recorded several sides for the new Danish Storyville label, including some featuring only Sunshine, Donegan and Barber on double bass. In 1959 the band's version of Sidney Bechet's "Petite Fleur", a clarinet solo by Monty Sunshine with Barber on string bass, spent twenty-four weeks in the UK Singles Charts, making it to No. 3 and selling over one million copies, and was awarded a gold disc. After 1959 he toured the United States many times (where "Petite Fleur" charted at #5).  In the late 1950s and early 1960s Barber was mainly responsible for arranging the first UK tours of blues artists Big Bill Broonzy, Sonny Terry and Brownie McGhee and Muddy Waters. This, with the encouragement of local enthusiasts such as Alexis Korner and John Mayall, sparked young musicians such as Peter Green, Eric Clapton and the Rolling Stones. British rhythm and blues powered the British invasion of the USA charts in the 1960s, yet Dixieland itself remained popular: in January 1963 the British music magazine, NME reported the biggest trad jazz event in Britain at Alexandra Palace. It included George Melly, Diz Disley, Acker Bilk, Alex Welsh, Kenny Ball, Ken Colyer, Sunshine, Bob Wallis, Bruce Turner, Mick Mulligan and Barber.  Barber stunned traditionalists in 1964 by introducing blues guitarist John Slaughter into the line up who, apart from a break between April 1978 and August 1986, when Roger Hill took over the spot, played in the band until shortly before his death in 2010. Barber next added a second clarinet/saxophone and this line-up continued until 1999. Then Barber added fellow trombonist/arranger Bob Hunt and another clarinet and trumpet. This eleven-man "Big Chris Barber Band" offered a broader range of music while reserving a spot in the programme for the traditional six-man New Orleans line-up.  A recording of the Lennon-McCartney composition "Catswalk" can be heard, retitled "Cat Call", on The Songs Lennon and McCartney Gave Away. Written by Paul McCartney the song was recorded in late July 1967 and released as a single in the UK on 20 October 1967.
