After playing for Jethro Tull from 1967 to 1970 (he recorded three albums), bassist [a=Glenn Cornick] left the band and formed Wild Turkey with the following musicians: [a=Glenn Cornick] (Bass), [a=Graham Hedley Williams] (Guitar), [a=Tweke Lewis] ( Guitar), [a=John Weathers] (Drums) and [a=Gary Pickford-Hopkins] (vocals). After a short period of time, the line-up was changed, Weathers and Williams left, replaced by [a= Jon Blackmore] (Guitar and Voice) and [a=Jeff Jones (2)] (Drums). This line-up features the album "Battle Hymn" on [l=Chrysalis Music], dated 1971 in Hard-Rock style with Progressive and Blues-Rock veins. The electric guitar and vocals are the protagonists, supported by a solid rhythm section and the record alternates more pushed tracks with other more melodic. The feedback is positive for both critics and audiences, thanks in part to their excellent live performances supporting bands such as Jethro Tull, Black Sabbath, Procol Harum, Yes, Ten Years After and Zz Top.
