An example starts off the proceedings in Hamateur Night, a 1938 cartoon for Warner Bros. A theatre pit conductor gets the attention of his musical crew.

Swiftly, Avery switches the situation and the musicians conduct the conductor.

His eyes extend when the slide on his trombone extends.
The number being played is “It Looks Like a Big Night Tonight” by Harry Williams and Egbert Van Alstyne. After one chorus, the conductor ducks down and switches instruments for a fanfare.

Being a professional of the theatre, he bows to the audience in appreciation.
Jack Miller is given a story credit, though we wonder how much he contributed as the gags are typical of Avery’s sense of humour. Paul Smith is the credited animator. Did Virgil Ross do this scene?
It’s good to see this cartoon has been restored. It’s one of Avery’s finer efforts for Leon Schlesinger.
