It's a question of degree, surely, and of how much coordination you need. Jim Morrison could get away with singing blind drunk, simply cos singing doesn't need much coordination. But the thought of trying to play a pedal steel after a couple of beers is scarey, cos you need so much more coordination.

I make sure that if I'm going to play I'll never have more than 2 or 3 beers, and after 2 I'm no longer as good with my fingers. After that, I'll give up and just join in the choruses. Anyone else with me on this kind of theory? After all, sometimes you feel like playing all night, and sometimes you just want to sit in the corner, mellow out and listen.

Grab.
