Let's Sing With Popeye is a 1934 Screen Songs animated short, produced by Fleischer Studios and directed by Dave Fleischer. The song featured in this cartoon was the Popeye theme song "I'm Popeye the Sailor Man", written by Sammy Lerner. The animation for this film is taken from the first Popeye cartoon, Popeye the Sailor, which was originally presented as part of the Betty Boop series.
