After fronting some regional bands in the south, he joined the Elvin Bishop Group and sang their No. 3 hit "Fooled Around and Fell in Love." He was asked to join Jefferson Starship in 1979 to replace Marty Balin and take co-lead vocals with Grace Slick.
In 1985 the band shortened their name to Starship and turned to a decidedly more pop sound. The No. 1 song, "Sara," from the new version of the band was sung only by Thomas with Slick providing just the backing vocals.
Mickey Thomas turns 63 today.
