the gigs that stick in my mind (sort of) are the free parties and raves we used to do. everyone there is there to have a hassle free good time, and dance! (do you notice people are getting more and more self concious about that these days?)
there was one the drummer often talks about, when we're playing a particularly hectic bit, he looks up and can't see any of the 3 of up (2 guitars, bass), he sees 2 leads going off into the crowd and catches Tims head bouncing up and down out then, and then sees someone pouring vodka down my throat, but still no sign of Ben, he then spots him lying on the floor of the stage doing his solo! when we come to our senses and return to the stage/stand up, an older gentleman comes up with a saxamafone and asks if he can join in. this gentleman used to play in a little band called Hawkwind, and proceded to blast out some sweet sweet sounds over some improve funk. we played for a few hours (literally until i could barely stand), and finished to a fierce roar of applause and cheering.
it felt [i]very, [b]very[/b] [/i]good in fact, i've got goosebumps just thinking about it!
