In the show from Yokohama 1996 which was aired on TV, there are two funny mistakes: In "Keep The Faith", after the solo, Richie starts his high notes in a wrong key which makes Jon looking confused over to Richie's side.
Later in "My Guitar lies bleeding in my arms" there's the part after the second chorus where they should go into that heavy riff which leads to the solo, but instead the band calms down like they do after the first chorus - only Jon hammers the riff on his acoustic. Sounds funny. But they manage it by kicking into that riff a bit later so it doesn't sound any bad, just not how it was intended to be. I compared it to one of the other Yokohama shows, where they play it like on the record. I always liked this part and how they saved it.

On the Bounce-Gig from Shepherd's Bush the change from "Cpt. Crash" into "I'll Sleep When I'm Dead" sounds a bit messed up, and on a bootleg from 1993 (Milton Keynes I think) Tico messes up the intro of "Wild In The Streets" a bit.

Otherwise I don't know much mistakes from them.
