It went great! Everything went very well. The soundman knew hwat he was doing and the sound was pretty much spot on from what I know. I was really nervous before soundcheck but we played a couple of songs during soudncheck and everything went flawlessly so the pressure was off and I was more excited to go on stage after that than nervous.
I did walk around with my bass but since there were absolutly no single women there the ladeeez socializing part didn't go so well.
It was a ton of fun and I hope we'll be able to do it again in the future, especially since we know we can do it pretty well.
Only thing that went wrong: Obviously, Final Countdown. The singer started ad-libbing when the song stops for an instant and he wanted the crowd to sing a bar of the chorus but it took us completly off guard and we all started the songs back off-time with everybody playing at a different beat basically. I believe I didn't do so badly because I followed what the drummer was doing, which is normally my job anyway.
