Cornwall, the Crying Crooner
Young, nerdy-looking singing star popular with the ladies in the "Everything's Relative" story of comic book The Kilroys #53 (April 1955). His real name is Gallileo. He visits his cousin Buster, who doesn't recognize him and thinks he's a real "schnookle." That is, until Gallileo pays for a coke with a fifty dollar bill.
Cornwall's mother's is Astradome.
