Luther was one of the main vocalists for this Disco studio group. Hot Butterfly was Luther’s first featured studio group recording in 1978. A Timeless classic and later recorded by David Lasley (Gregg Diamond asked him to take a swing at it after Luther recorded it since David was on the Hot Butterfly album as well providing background vocals and lead vocals on a song titled Paradise), The Sweet Inspirations (1979 Hot Butterfly LP a great album), and Chaka Khan. In 1979 Bionic Boogie’s last album TIGER TIGER has 2 songs co-written by Luther and Gregg Diamond with Luther singing lead vocals. Lay It On The Line and Crazy Lady Luck are worth listening too. I love Crazy Lady Luck it has fun and bouncy lyrics and I love the line: That’s her mother I’d like to have another please…I have a feeling that was a Gregg Diamond line.
