Same situation and song but the gags are totally different. Warner Bros. owes their whole sense of humor to Tex Avery anyway. If it wasn't for Tex they'd never have stopped copying Disney, so does that make things even?
Tex actually tried doing that 'hair in the projector' gag about a decade earlier in the Warner Brothers cartoon Aviation Vacation (1941), but the animation isn't nearly as good. Supposedly, they had to put a warning label on the Magical Maestro print cans to let the poor projectors know that hair was supposed to be there...
