20. "Sixty to Zero"
Unlike most of his peers, Young has never been afraid to try out unreleased songs in front of a live audience, even if the song isn't completely done. This was the case with "Sixty to Zero" in the summer of 1988, which was reworked the following year as "Crime in the City" on Freedom. The original was a full 20-minute epic played a mere 13 times in 1988. Thankfully, camcorders were a running and it's survived. For years it was only available for viewing on third-generation VHS tapes, but YouTube is an incredible thing.
