From 1953, please enjoy (unknown to all but the most devoted cogniscenti) greaseballs Sonny Dae and the Knights and the original recorded version of the song that started it all -- "Rock Around the Clock."
You know, I consider myself fairly knowledgeable about this sort of stuff, but I must confess, until today I had no idea this record existed, although I think I knew vaguely that somebody had cut the song earlier than Bill Haley. Actually, at least according to Wiki, the familiar Haley version is not technically a cover; the Tin Pan Alley pros who wrote the song apparently had Haley in mind when they penned it, but for whatever reason he was too busy to fit in into his schedule until 1954. And the rest, as they say, is bunk (i.e., history).
In any case, as always, a coveted PowerPop No-Prize will be awarded the first reader who gleans its relevance to the theme of tomorrow's Weekend Listomania.
