I had a great friend named Mark when I was growing up. We used to talk about music an awful lot. He was a huge Hall & Oates fan. He also was quite a Beatles fan. So, when the topic of this song came up, we had a lively debate as to which was the better version of the song - The Beatles' or Joe Cocker's. We never did come to consensus on that one, although, in his open-minded way - one of the most open-minded people I've ever met - he could accept that this version was more than a cover, but a reinvention of the song. It really is a different song.
Mark would have been 40 this month - he passed away in 1995. I think of him every time I hear this song.
And, for Mark, here is the original.
