Personally I like the Rockabilly version best. The "Blues piano" style sounds like a Elton John ripoff, the 50s version sounds like a cheeze 50s pop tune, the "Mellom" version doesn't give the song the kick it needs.

But I think the song needs a different bass line, that 2 feel oompaa oompaa bass doesn't drive the song that well. But thats only my opinion, it's your song I think your song would benifit from a 4 feel, up-tempo, slightly less busy, but maybe with a organ instead of strings.

But thats what I think, others might think differently, and all in all it is your song.
