I have a different theory. If you spend any time in music stores, you'll notice "regulars" who come in to do solo jams (usually the same tunes like Stairway or some Priest). In any case, I think some of these guys must have gotten together for a jam. But instead of going with something simple that any moron could do, like "You Really Got Me" from the Kinks, they tried to wing Floyd and came up with this disaster instead.
