Billy Lyall
William Lyall was a Scottish musician.
Born in Edinburgh, Scotland, Lyall was a keyboard player, vocalist and occasional flautist with Pilot, and an early member of the Bay City Rollers. He was keyboard player for Dollar between 1978 and 1982, and also contributed to The Alan Parsons Project with fellow Pilot members. He left Pilot in early 1976 and released a solo album, Solo Casting later that year. He also contributed string arrangements and synthesizer parts to an album by the band Runner in 1979.
Lyall died of AIDS-related causes in 1989, aged 36. Bay City Rollers' manager Tam Paton later said that Lyall was gay.
