I read an interview with Jon where he said that one time at a German show Tico started playing a completely different song to the one on the setlist.

Also, at Gateshead 2000 Jon mis-read the setlist and was ready to play one song when the band where ready for another (from memory Jon was expecting Mystery Train when the others where ready for It's My Life) - Jon simply laughed and explained that he had drunk too much the day before in London and that he only wrote the setlist - he didn't read it.
