Well, I managed to somehow keep calm despite the nerves trying their best to make me screw up. It wasn't my best playing ever, but it was the first time I tried playing for strangers without sitting in a guitar-store, testing either guitars, pedals or amps (or any combination of those) :) Thanks for the great article. I did screw up during the song I was playing along to, but nobody seemed to notice, so who cares?
