Re: Rockabilly
I don't know that I agree with your brief history of rockabilly. "Rocket 88" was the first major release on Sun records, the famous rockabilly label, but it was not really a rockabilly song. It was (and still is) generally accepted as an RnB song and maybe, just maybe, an early rock'n'roll song. It does not really have any of the trademarks or rockabilly music per se.
Plus, even if you want to consider it a rockabilly song it is still not fair to say that rockabilly itself started back in 1951 because there was a gap before anything generally accepted as rockabilly actually surfaced. I would place its inception closer to 1955 with it really "exploding" in 1956. Granted, it is sometimes tough to say where country and honky tonk type music actually mutated into rockabilly so it is not really relevant to argue over exact dates. One early crossover artist worth looking into is Charlie Feathers who was acutally writing and recording before Elvis really got started and wrote a number of classic rockabilly tunes. As for Elvis, he is probably one of the first bonafide rockabilly artists (along with Carl Perkins, one of my personal favorites), although he quickly moved out of that area after he left Sun records.
As for the resurgence of rockabilly in the form of neo I would like to mention a band called Buzz and the Flyers. They actually came before the Stray Cats and were one of the most influential neo bands, although they are quite overlooked in my opinion. They influenced The Stray Cats, Rockats and Polecats (among others). However, it was certainly the Stray Cats who popularized the rockabilly resurgence.
I was so pleased to see a mention of rockabilly on this page that I just had to take part in the discussion. I hope what I have said is helpful.
