the most embarassing thing that happened to me was when i was playin in a school gig. we were playing the song 18 and a life by Skid Row (great band!) and when i was juz abt to play the solo part....my first bend of the string....it snapped....and i was like..."eerrr **** **** damn...arghh" so i juz smiled...quickly juz picked a few notes somehwere else on the guitar...then continued wif the song. the crowd was like laughing their asses off at my reaction.
but other then dat..things went quite smoothly for all other gigs.
