Adrenalin was a seven-piece arena rock group assembled in 1984 by singer Marc Gilbert, guitarists Flash and Michael Romeo, saxophonist Jimmy Romeo, keyboard player Marc Pastoria, bassist Bruce Schafer, and drummer Brian Pastoria that made two albums for MCA in 1985 and 1986. In 1987, Gilbert and Flash left and were replaced by ex-Grand Funk singer/guitarist Mark Farner, who stayed a year and was replaced by singer Joey Hammody. ~ William Ruhlmann
