Okay, well Mark came out and played bass for The Vandals during one of their songs so that was really cool.
And when they first played Blow Job they got the whole crowd to sing along, then after the next song Mark was saying Tom played it in the wrong key so they played it again, then Mark and Brooks kept playing after Tom had finished, until he was forced to sing it again, so it kind of became this funny running joke where they'd always play Blow Job. Even in their acoustic set, Mark was supposed to start Wasting Time, but him and Brooks started Blow Job instead.
And I was totally surprised to hear STFTK, Mark started it off by saying "We haven't played this song for a few years, so if we stuff it up, it's Brook's fault"
And Tom and Mark were cracking each other up during the acoustic set, which awesome to see.
Probably one of the best concerts I've been too, plus Mark came out to the stage at after the show and handed some things out to fan, but I missed out, haha.
