I think Lou Levy is one of the West Coast jazz veterans whose work since 1975 has been overlooked. While he has released several excellent albums as a bandleader, I feel he was essentially the house pianist for West Coast jazz from the 1970s onward. He also appeared on many Atlas recordings.
I’ve always assumed that cue was either library-style material or something Laurie Johnson himself supplied. He worked on the film and specialized in that exact kind of polished, radio-friendly jazz that sounds real but doesn’t draw attention - basically perfect for that scene.
