Davey Pattison (born November 18, 1945 in Scotland) is a San Francisco Bay Area based rock vocalist. Pattison recorded his first music in 1969, and his career took off after arrival in the United States in 1979, on invitation from Bill Graham, to front the band Gamma, formed by Bay Area guitarist Ronnie Montrose."I'd given up all hope of finding a quality singer for Gamma until I heard Davey Pattison," according to Montrose.
