75年的母带'Peg Leg - The Lost Tapes', 被扔在Stebbing的仓库里，经过了漫长的整理和重录，终于在2001年发行了CD专辑
From late 1971, Maurice divided his time between his music and nightclub construction with his brothers, Barry and Frank. They were responsible for opening quite a few clubs in Auckland, notably Hatchett's, Granny's, Shantytown, Ruby's Saloon and Croft's, as well as quite a number of others around the country.
Human Instinct released another single 'Texas Sparrow'/'Children Of The World' in 1971 and two more albums. One in 1972 called 'Snatmin Cuthin' and the other in 1974 called 'The Hustler'.
1972 saw a single on the Zodiac label called 'Down The Hall On Saturday Night'/'Simple Man' and then in 1975 the final single on Family 'Tropical Paradise'/'Dixie Holiday'.
Between 1972 and 1982 there were many combinations of the group. Others to have had a stint with the band were Paul Whitehead, Steve McDonald, Peter Cuddihy, Andrew Kaye, Chris Gunn, John Parker, Malcolm Weatherall, Len Whittle, Kevin Fury, Steve Hubbard, Murray Hancox, Stuart Pearce and Peter Woods.
Around 1982, the Human Instinct was formally disbanded by Maurice Greer. After his time with the band, Billy TK went on to form Powerhouse.
Recently the first three albums by Human Instinct have been re-issued on CD by Ascension Records, along with a CD of all of their singles.
In late 1975, when the line-up consisted of Greer on drums, Whitehead on guitar, Mikkelson on bass, and McDonald on keyboards, a recording session for an impending album was done. The group at that time had been playing together for around 18 months at the Shantytown nightclub under Auckland's Civic Theatre. Several months passed before a rough mix-down of the tapes were performed. By the time the sessions were finished, the Human Instinct had moved on to a new residency at Crofts and there style of music had changed, along with new members in the band. The project was subsequently shelved.
In 2001, the session tapes were located at Stebbing's warehouse and a long slow process of restoring and re-mastering the tapes took place with the final result being the release of that 1975 album on CD called 'Peg Leg - The Lost Tapes'.
