Tiny Tim & the Non-Rehearsal

Tiny Tim was one of the most unusual acts I ever played. never mind the visual aspect - I'm not referring to that part. Most successful entertainers have an "image" that they use/are. One quickly becomes accustomed to that part of the biz. (There's an old expression - You're always on stage. Pros recognize the truth of that and act accordingly. It's only the Jung and Fuelish who haven't figured it out, or choose to disregard it, usually with negative career consequences.)
But back to Tim...Rehearsal was scheduled for 4:00 PM and the 4 of us are there, ready for goodness-knows-what. So up to the stage ambles Tim, somewhat beat-up ukelele case in hand. Says, hi to everybody - in a voice noticeably deeper than the counter-tenor that was his recognizable singing voice. And out comes the uke. OK.
"So where's your music?"
"Don't have music. Don't use any." - oboy, this is going to be fun. - "We'll just play some tunes, and you follow me." - oboy, this is going to be BAD; a train-wreck in the making for sure - "Let's see - do you know Baby Face? In D." - Geez, what kind of show is this? - (After about 30 seconds of Baby Face) "OK that's fine. That's enough. Tonight, just follow me." - OBOY; this is no train-wreck, this is going to be a disaster - "See you guys later."
And that was the rehearsal. For the world-famous Tiny Tim.
And the show? Well, we followed him; sort-of. He would name some really obscure tune from, say, 1908, give a little history of it, and launch into the verse. No key, no form, no nothing. Nada. And we would attempt to follow him. Of course, none of us actually knew the tune. And repeat the same procedure with a different tune, from 1912. Etc. etc. etc.
A train-wreck? You bet. Multiple train-wrecks. But guess what - when the audience doesn't know the tunes either - nobody knew they were train-wrecks. And in the famous words of the late Tom Borshuk (long gone now) "Nobody Died!"
