Once had a drummer answer an ad. At that time we were semi-pro. He said he was more of a jazz drummer but could play all styles. We picked him and his drums up, lugged them and their cases up the narrow attic steps to where we rehearsed and watched him set up his impressive kit in anticipation.
Finally, it came to the time where we would play one of the songs we had given to him on cassette a week earlier. Two second later, it becomes apparent that this clown cannot play at all! He was the worst I have ever heard. Maybe it was some obscure jazz he played? No, turns out he was a rich kid living in fantasy land. He literally sounded like a five year old picking up sticks for the first time! Now normally I'm very patient in rehearsals but not this day. I had to look at the singer and say "Get him flipping out of here before I throw him and his kit down the stairs".
Now that would have sounded like jazz!
