In 1971, bassist Steve Davy left the band, and Louis Cennamo was recruited as his replacement - then, vocalist/guitarist Kieran White also left after a summer tour. Guitarist Martin Pugh, drummer Mick Bradley and Cennamo (with guest vocalist Garth Watt-Roy, of Fuzzy Duck) then went in the studio to record Speech, which was released in 1972. It consisted of three lengthy (and mostly instrumental) songs in a heavier progressive-rock vein, that was somewhat different from their initial blues and folk/jazz-influenced albums.[2]
Bradley died from leukemia shortly before the album's mixing was completed (the album is dedicated to him on the inside album cover). The band continued with American singer/guitarist Bruce Payne and drummer John Lingwood, touring in Germany in support of the album, where they were more popular than back home in England.[3]
