Round where I live, (Northern NSW) we have heaps of old village halls built around 100 years ago, well before PA was invented. Most have great acoustics and you can stand on stage and speak or sing..everyone in the hall can hear you clear as a bell.
Nowadays whenever there is a gig, in come the truckloads of speaker stacks and racks of electronics. Result is always the aformentioned "wall of shit" most of the punters are outside getting away from the noise until late on when they are pissed and stoned enough to come back in for a dance. Long as that happens the gig is judged a success.
Ask the sound man nicely if he could adjust the levels so we can perhaps have an idea of what the words to the song might be and you will be advised to GFYS.
