Two of my all-time favorite Beatles tracks and both from the best album in their entire catalog (IMHO).
The Joe Cocker version of Something was kinda wonky. The first couple of lines were a bit shakey but it came together I think in a decent style that is Cocker's style, but the keyboards throughout the song from the too-long intro on to the end of the song are quite annoying and are misplaced... just the wrong sound for that song. Cocker was ok though, once he got going.
I like Graham Bonnet, cool set of pipes, but his version sounds almost forced. The music in his cover isn't nearly as annoying as the first track in the poll, so I guess I'll give my vote to Oh Darling. I'm with LG as I don't think either cover even remotely compares to the originals.
