theres a chance, but its not guaranteed just cos its a first time, the worse thing that might go wrong is u forget ur lyrics, no matter how well u kno em we've all done it at some point, if that happens, do NOT stop, just freestyle ur way through it, if u let the crowed notice uve fucked up, u are pretty fucked, but when ive got a gig coming up, i allways practice every night for about 2-3 hours for a week before the gig to make sure that everything is set, everything is known e.t.c to make sure that the chances of fucking up are minimal.

if u get nervous, have a few beers before hand, dont get drunk, but just a couple for that "dutch courage" n ull be fine
