Input: A cover of ``Long Tall Sally'' followed in the spring of 1966, by which point the group had parted with Roman (who subsequently became program director of CKFH) and signed up with Bernie Finkelstein (later Bruce Cockburn's longstanding manager). However, shortly after a show at the El Patio on July 24, 1966, Marion left and subsequently recorded a solo single before moving into production work and playing with The Last Words. In _his_ place, The Paupers recruited Scottish *migr* Adam Mitchell (born November 24, 1944 in Glasgow, Strathclyde, Scotland, resident of Bolton, Ontario) from the CommonFolk (a folk group featuring Doug Bush, Ian Rankin and Bruce Whitehead), apparently on an hour and a half's notice. <sep>, Pronoun: his <sep>, A: Adam Mitchell <sep>, B: Doug Bush
