True Jacqui - though if you've paid to get in, you might put up with it. Beer, coke, lemonade... the more whistles wetted, the higher the take.
Another angle to this I heard from a friend's son who started an acoustic based Irish group, but found within 2 months they had to electrify and add bass and drums, a la your standard pub band, to get any bookings in licenced premises.
Now, you'd expect an Irish band is going to be noisy, but this was probably to add amplification possibilities of electric bass and a drumkit. The volume goes up, shouting ensues, throats get parched, liquid gets bought and downed. "Thems the paying gigs!"
