Mick did mention in his book that he loved it on the album, so I'm sure it was his idea. I don't hate it & whenever I listen to the album, I don't skip it. The best thing you can say about it is it isn't very long.
I would have liked to have had one of Christine's terrific songs from the Madison Blues box set instead. I think "Gone Into The Sun" would have sounded fantastic as the album closer.
