A movement of 4 : Samuel, Jonnie, Ottay, and Bolla (EMI Nigeria). I don't remember where I picked this up, probably at Papa Disco's shop in Cotonou. It's one of those albums you simply want to buy because of the cover and a song called 'Stone Funk' always gets my attention!
P.S. Miles Cleret and Hugo Mendez at Soundway Records are going to release another Nigerian compilation, 'Nigeria Special: Highlife, Afro-Sounds & Nigerian Blues 1970-1976 (Summer 2007).
