Billy Lyall, (William Lyall) 3/26/53 – 12/01/89.
Billy was born in Edinburgh, Scotland. He was the keyboard player and vocalist. Billy was an early member of the Bay City Rollers. He died of AIDS. Billy was 36.
I have found very little information on Billy and don't know much about him. I hope someone who does comes across this and can share more here.
