Answer by taking a quote from the following article:

Skyhooks were an Australian rock band formed in Melbourne in March 1973 by mainstays Greg Macainsh on bass guitar and backing vocals, and Imants "Freddie" Strauks on drums. They were soon joined by Bob "Bongo" Starkie on guitar and backing vocals, and Red Symons on guitar, vocals and keyboards; Graeme "Shirley" Strachan became lead vocalist in March 1974. Described as a glam rock band, because of flamboyant costumes and make-up, Skyhooks addressed teenage issues including buying drugs "Carlton (Lygon Street Limbo)", suburban sex "Balwyn Calling", the gay scene "Toorak Cowboy" and loss of girlfriends "Somewhere in Sydney" by namechecking Australian locales.

Greg Macainsh and Imants "Freddie" Strauks both attended Norwood High School in the Melbourne suburb of Ringwood and formed Spare Parts in 1966 with Macainsh on bass guitar and Strauks on lead vocals. Spare Parts was followed by Sound Pump in 1968, Macainsh formed Reuben Tice in Eltham, with Tony Williams on vocals. By 1970 Macainsh was back with Strauks, now on drums, first in Claptrap and by 1971 in Frame which had Graeme "Shirley" Strachan as lead vocalist. Frame also included Pat O'Brien on guitar and Cynthio Ooms on guitar. Strachan had befriended Strauks earlier--he sang with Strauks on the way to parties--and was asked to join Claptrap which was renamed as Frame. Strachan stayed in Frame for about 18 months but left for a career in carpentry and a hobby of surfing in Phillip Island.  Skyhooks formed in March 1973 in Melbourne with Steve Hill on vocals (ex-Lillee), Peter Ingliss on guitar (The Captain Matchbox Whoopee Band), Macainsh on bass guitar and backing vocals, Peter Starkie on guitar and backing vocals (Lipp & the Double Dekker Brothers) and Strauks on drums and backing vocals. The name, Skyhooks, came from a fictional organisation in the 1956 film Earth vs. the Flying Saucers. Their first gig was on 16 April 1973 at St Jude's Church hall in Carlton. At a later gig, former Daddy Cool frontman, Ross Wilson was playing in his group Mighty Kong with Skyhooks as a support act. Wilson was impressed with the fledgling band and signed Macainsh to a publishing deal. In August, Bob "Bongo" Starkie (Mary Jane Union) on guitar replaced his older brother Peter (later in Jo Jo Zep & The Falcons) and Ingliss was replaced by Red Symons (Scumbag) on guitar, vocals and keyboards. The two new members added a touch of theatre and humour to the band's visual presence. By late 1973, Wilson had convinced Michael Gudinski to sign the band to his booking agency, Australian Entertainment Exchange, and eventually to Gudinski's label, Mushroom Records.  Skyhooks gained a cult following around Melbourne including university intelligentsia and pub rockers, but a poorly received show at the January 1974 Sunbury Pop Festival saw the group booed off stage. Two tracks from their live set, "Hey What's the Matter?" and "Love on the Radio" appeared on Mushroom's Highlights of Sunbury '74. After seeing his performance on TV, Hill phoned Macainsh and resigned. To replace Hill, in March, Macainsh recruited occasional singer, surfer and carpenter Strachan from his Frame era. Strachan had been dubbed "Shirley" by fellow surfers due to his curly blond hair a la Shirley Temple.

Did anything bad happen in the early years?
