Itunes can do funny things to you. Before I had all my music on my computer, I would never have been able to work out which song I have most different recordings of. I would have wondered, but I never would have actually been able to work it out.
I assumed the answer would be Yesterday - as that is, I believe, the most recorded song of all time. But I've only got four different recordings of that in my collection - The Beatles, Paul McCartney doing a later, live version, Ray Charles and Oscar Peterson.
I have five different recordings of Summertime: Ella Fitzgerald, Miles Davis, Gary Burton, Oscar Peterson and, weirdly, Peter Gabriel.
But so far, the surprise winner is Georgia On My Mind. I have six different recordings of it. I'm still looking for other songs that I might have loads of different times, so feel free to suggest titles I should search for.
Meanwhile, how about guessing which 6 recordings I have?
