"I remember when rock was young." They probably never play Speedy Gonzales on the radio anymore--it's absurdly politically incorrect by today's standards--but people ought to know that Crocodile Rock completely borrows from Pat Boone's novelty hit. John Stevens is kind of a Pat Boone type, so conceivably that connection led him to choose that song.
And let me point out another the Clay Aiken-Grease/John Stevens-Crocodile Rock similarity: they both conspicuously wore red jackets. And both, previously non-dancers, let loose with some weird dance moves. Judges were equally skeeved by both redheads.
Oh, and what about Speedy Gonzales the cartoon character? Should he be banned?
