Background: The Four Tops are a vocal quartet from Detroit, Michigan, USA, who helped to define the city's Motown sound of the 1960s. The group's repertoire has included soul music, R&B, disco, adult contemporary, doo-wop, jazz, and show tunes. Founded as the Four Aims, lead singer Levi Stubbs, Abdul "Duke" Fakir, Renaldo "Obie" Benson and Lawrence Payton remained together for over four decades, performing from 1953 until 1997 without a change in personnel. The Four Tops were among a number of groups, including the Miracles, the Marvelettes, Martha and the Vandellas, the Temptations, and the Supremes, who established the Motown Sound heard around the world during the 1960s.
Context: Motown as a company began to change during the early 1970s. Older acts such as Martha and the Vandellas and The Marvelettes were slowly moved aside or dropped to focus on newer acts, such as Michael Jackson and The Jackson 5, Rare Earth, and the now-solo Diana Ross. In addition, the company moved its operations from Detroit to Los Angeles, California, where Berry Gordy planned to break into the motion picture and television industries. In 1972, it was announced that the entire company would move west and that all its artists had to move as well. Many of the older Motown acts, already neglected by the label, opted to stay in Detroit, including The Funk Brothers studio backing band, Martha Reeves, and the Four Tops.  The Tops departed Motown for ABC-Dunhill, where they were assigned to writer-producers Dennis Lambert and Brian Potter and the label's head of A&R, Steve Barri as producer, with The Tops' own Lawrence Payton later also serving as a producer and writer. He also took over lead vocal duties on several tracks.  The group's first release on the label, "Keeper of the Castle" was their first pop Top 10 hit since "Bernadette" in 1967. Follow-ups included the million-selling "Ain't No Woman (Like the One I've Got)", also a top 10 pop hit and their third R&B number 1, and the Top 20 hit, "Are You Man Enough", (from the movie "Shaft in Africa"). "Sweet Understanding Love"; "Midnight Flower"; and "One Chain Don't Make No Prison" all reached the R&B Top 10 between 1972 and 1974. Two ABC/Dunhill singles, 1974's "I Just Can't Get You Out of My Mind" and 1975's "Seven Lonely Nights" have become popular tunes in the southeast Beach/Shag Club Dance circuit.  After the release of "Catfish" (a top 10 R&B hit) in 1976, the major hits started to dry up and the Tops left ABC after an album recorded in Philadelphia with the MFSB musicians resulted in only minor chart success in 1978. The group disappeared from the recording scene until the early 1980s. Signing a deal with Casablanca Records, the Tops made a comeback in 1981 with the #1 R&B hit "When She Was My Girl". Produced by David Wolfert, it just missed the Billboard pop Top 10, peaking at #11. The group also scored a UK Top 10 hit with the song and had another hit there with the follow-up, "Don't Walk Away".
Question: Why  did they depart motown?
Answer: In 1972, it was announced that the entire company would move west and that all its artists had to move as well.

Problem: Background: Mental As Anything are an Australian new wave/pop rock band that formed in Sydney in 1976. Its most popular line-up (which lasted from 1977-1999) was Martin Plaza (birth name Martin Murphy) on vocals and guitar; Reg Mombassa (birth name Chris O'Doherty) on lead guitar and vocals; his brother Peter "Yoga Dog" O'Doherty on bass guitar and vocals; Wayne de Lisle (birth name David Twohill) on drums; and Andrew "Greedy" Smith on vocals, keyboards and harmonica.
Context: During the sabbatical, Mental As Anything still played short tours and one off gigs, but by 1993 they were back on record, providing the song "Ride", produced by Tim Farriss, for the soundtrack to the Yahoo Serious film Reckless Kelly. They released a compilation of rare album tracks and b-sides, Chemical Travel, in November.  By mid-1994 the band had recorded an album's worth of self-produced material but were having difficulty getting a release deal. They self-released an EP of songs, Bicycle, and gave it away on their summer 1994/95 tour of NSW and Queensland. Radio station Triple J received a copy of the Bicycle EP on Christmas Day 1994 and put the lead track "Mr Natural" on immediate heavy rotation. Other stations followed and the demand led to the track being given a commercial release as a single and reaching the top 30 on the ARIA Charts (although charting higher in the States where the tour and free EP didn't reach). The resulting album, 1995's Liar, Liar Pants on Fire, reached the top 40, with Mombassa's cover taking the 'Best Cover Art' award at the 1996 ARIA Music Awards.  Three further singles were lifted off Liar Liar in 1995 and 1996: Mombassa's "Nigel" which just failed to chart, a cover of Wreckless Eric's "Whole Wide World" which landed just out of the Top 50 (Top 30 in Victoria) and O'Doherty's tribute to Ms Faithful, "Marianne", which was released as the band supported Chris Issak on his 1996 tour of Australia.  On 16 August 1997, Mental As Anything celebrated 20 years together with the same line-up with a free birthday show at the Hopetoun Hotel in Sydney. Late 1997 saw the band put together their third group art exhibition, Mentals III, which was opened by former Prime Minister, Gough Whitlam, at the Manly Art Gallery (Paul Keating had opened their second group exhibition in 1990). Their 21st anniversary in 1998 was marked with the release of the last album by this line-up, Garage, which did not reach the top 50, nor did the two singles lifted from it, "Just My Luck" and "Calling Colin". December 1999 saw the release of Best of Mental As Anything which was accredited by ARIA with a gold certificate by 2001, and a seasonal single "White Christmas", that was given away at their "Yule Party" gig at Sydney's Metro Theatre.
