In case you didn't know (and not that it really matters), besides the vocals being overdubbed, Randy's solo spot is not the one that was performed at that particular show. It was taken from a concert from Montreal that was aired on The King Biscuit Flower Hour radio show. (I recorded the original broadcast in the 80's and still have it on cassette....I think). The obvious signs are the brief pauses at the very beginning and end of the solo and Randy's guitar suddenly being tuned down half a step (Tribute's version of Suicide Solution is in standard tuning, while it's a half step down at the Montreal show).
Here's the solo from the original Montreal show:
