Clifford Everett "Bud" Shank Jr. was an American alto saxophonist and flautist. He rose to prominence in the early 1950s playing lead alto and flute in Stan Kenton's Innovations in Modern Music Orchestra and throughout the decade worked in various small jazz combos. He spent the 1960s as a first-call studio musician in Hollywood. In the 1970s and 1980s, he performed regularly with the L. A. Four. Shank ultimately abandoned the flute to focus exclusively on playing jazz on the alto saxophone. He also recorded on tenor and baritone sax. His most famous recording is probably the version of "Harlem Nocturne" used as the theme song in Mickey Spillane's Mike Hammer. He is also known for the soundtrack recordings with his group to the surfing films of Bruce Brown in the late 1950s and early 1960s, and for the alto flute solo on the song "California Dreamin'" recorded by the Mamas & the Papas in 1965.
