 The band played its first gig in May 1967, and had its first major break at the 7th National Jazz and Blues Festival in Windsor on 13 August. Oldham had managed to secure a separate set for the group in a side tent away from also accompanying Arnold on the main stage, where they gained attention. The next week, Welch wrote in the Melody Maker that "it was the first time I had seen a group actually in the act of winning its first following in quite dramatic circumstances." When Arnold went back to her family in the US shortly afterwards, Oldham offered the group a contract of their own. Hague was not interested in the "progressive" direction the group wanted to go in, so he was replaced by former Mark Leeman Five and Habits drummer Brian Davison.
