Cat Stevens' cover of Another Saturday Night is the definitve version in my mind. I think the original was by Sam Cooke.
LOL - I grew up listening to both versions. In what has to be as good a case of sitting on the fence, I have to say that I think both versions are excellent. Cat Stevens had the advantage of better backing music, but Sam Cooke is one of the all time classic voices in Soul. He is on a par with Marvin Gaye, and very few others.
I just discovered a really good cover of Janis Ian's At Seventeen. It is done by a girl from New Zealand, by the name of Amber Claire. I don't know many songs that feature an accordian, but this cover does, and the girl has a really sweet voice: YouTube - At 17 - Amber Claire
PS - the girl playing the bass guitar is pretty easy on the eyes, too.
