Texan Wesley Erwin "Mac" Curtis, Jr. fronted a Rockabilly trio when he was in high school. One of their shows was stopped due to the 'lewd and sexually suggestive' gyrations that Mac made on stage.
There's a story that has a friend of Mac's interrupting a practice session with the news 'there's a guy that sounds like you and he's got a record on the jukebox at the Dairy Queen'- the record in question being by Elvis Presley.
Mac played on Alan Freed's 1956 Xmas show while still at high school.
Here are some sides that Mac cut for the King label in 1956 and 1957.
