The Gass was a rock band formed in May 1965 by Robert Tench, Godfrey McLean, and Errol McLean. They were managed by Rik Gunnell and Active Management. The band fused melodies with soul, latin influences, blues and progressive rock often employing complex rhythms.
The original line up was Robert Tench on bass guitar, percussionist Errol McLean, his brother drummer and vocalist Godfrey McLean, saxophonist Humphrey Oka and guitarist Alan Roskans. Tench soon became the band's vocalist and lead guitarist and between 1965 and 1967 they released singles on theParlophoneandCBS labels and as their music progressed the line up changed. They also played at clubs and venues in U.K and at fashionable music venues in London's Soho such as The Ad Lib club, The Flamingo and the Bag O'Nails. Eric Burdon sang with them at The Scotch of St James where they were employed as the house band and Jimmy Hendrix jammed with them. During 1968 they were supporting bands such as Led Zeppelin and became the backing band for Catch My Soul-Rock Othello produced by Jack Good. By this time they were known simply as Gass.
The band released their first album Juju (1970) which featured guitarist Peter Green. and in the same year Godfrey McLean appeared on Peter Green's End of the Game (1970). Gass were also featured on the album Catch My Soul (1971), which was recorded with the original cast of the UK stage production of Catch My Soul-Rock Othello.
In 1971 the band recorded the single "Something's Got To Change Your Ways" which was released the Polydor label. Pete Masden mentions in his book, Funk Guitar And Bass, that during this period Godfrey McLean and Tench performed at regular jam sessions with other musicians at Ronnie Scott's club. These sessions led to an embryonic line up for the fusion band Gonzalez.
In May 1971 Tench joined The Jeff Beck Group and Gass finally disbanded. Godfrey McLean recorded with Brian Auger and The Oblivion Express.Delisle Harper who was the band's bass player in a later lineup appeared with Tench on Freddie King's Burglar (1974) also Larger than Life (1975).
