From the animated kids' show Oswald. Anthropomorphic, fedora and bowtie-clad singing starfish who hosts his own television variety show. He sings, swings, and slings slang like a Rat Pack era Frank Sinatra.
He gives a concert in Big City, and Oswald is last in line after holding places for his friends and doesn't get a ticket cause they're sold out. Then he helps a worker move a piano onto the stage and ends up playing for him.
Sammy's drummer is a squid.
Madame Butterfly mentions one his songs, "What's New Kittycat."
The Bunny Quartet performed on his show. Performance not shown.
