Like Jimi Hendrix, Lewis is part of the Jackson Street pantheon more by association and lineage than by direct participation in the old jazz scene, though he did achieve his widest local fame playing at Birdland, a club that succeeded the Savoy Ballroom at 21st Avenue South and East Madison Street. Lewis’ father, also named Dave Lewis, played guitar and migrated west for war work in Bremerton at the same time Quincy Jones’ family did, and the elder Lewis gave Jones a few musical pointers. The younger Lewis attended Garfield High School and Franklin High School and formed a combo that opened for traveling rock’n’roll stars such as Bill Haley and the Comets. With a trio featuring infuential Seattle electric guitarist Joe Johansen, Lewis scored regional hits in 1962, with “David’s Mood,” and in 1964, with “Little Green Thing.” Though he continued to appear at venues such as the Black and Tan and Sonny Booker’s Checkmate, Booker declined in popularity as tastes changed and he eventually fell into drug addiction and did prison time.
