Sonny West actually had the camera focus on him in this film. He is in the scene where Doc is searching the parked cars looking for Valerie and Romano.

Alan Fortas can be spotted standing at the bar during the "wolf call" number at the end of the movie. He is second on the left.

Richard Davis is also in this last scene. He can be seen standing just behind Elvis (on the left).

It's interesting that on the 1988 Turner video package, the film date is listed as 1964. That is when the film was made, however it was not released in the U.S. until 1965.
