I played in a band where the drummer used to smoke three doobies before the last set. He always played okay, not a lot of difference.

well, one night, he must have got an especially potent batch, and after the usual three doobies, we got started on the last set.

Several times during the set, in the middle of a tune, he try and catch my eye, and when he did, he'd look at me wide eyed and mouth the words, "What song are we playin?"

Still gives me a chuckle thinking of the look of panic on his face.
