My father had every record by Homer and Jethro he could find.

UB: another brilliant post, as usual.
 
I thought about including roadies and FOH mixers, but the band doesn't consider them musicians (even if they're better players than the poseurs on stage). Still, back when I had the luxury of having real roadies (not somebody's roommate who works for beer), they tended to be the most level-headed people in the enterprise. You could usually count on a roadie to be the only one sober enough to trust behind the wheel.
 
As far as FOH guys, I have mixed feelings.
 
A good live mixer is worth his weight in cocaine. A bad one is worse than useless. The problem is, pretty much anybody who can write on a piece of tape without getting marker ink on the console seems to qualify as a live mix engineer. I have attended performances where the mix was just awful, where mics were feeding back and everything sounded like a bass solo on one string - and the mixer's flirting with a groupie, oblivious. Yeh, babe, I'm with the band. They couldn't function without me.
 
A good engineer is a lifesaver. Musicians tend to be technologically inept, and need someone to suggest that instead of smashing that transmitter maybe they could just try a fresh battery. And then actually be able to produce said battery.
 
I'm waiting for Karyn to weigh in.

Everyone left  banjo players off the lists.......And probably with good reason..... I guess that's because someone gave him the address to the gig... but it just happened to be in a city 50 miles in the other direction from the actual gig.....
 
But on the positive side, his instrument can be used to pound railroad spikes if you need a hammer in a pinch.

Wow,  I didn't know you'd been to one/some/all of my shows.
 
I solved the marker pen on the desk problem (and the writing problem),  with magnetic tags.

I'm waiting to work off Xmas dinner first...

Audio Engineer: I work with morons. Not the clever, creative, or cute morons, mind you. No. (sigh) "Your vocal is already up in your monitor, the reason you can't hear yourself is because you're holding the mic two feet away from your mouth." "Oh no. Don't you glare at me because you played the wrong chord. Maybe if you showed up for a rehearsal once in a while you'd know how to play the songs." I used to have dreams, you know. I wanted to work in a nice studio with great musicians and be a part of making some audio magic. Instead, I'm running sound for a band that shouldn't be allowed to play for the Grand Opening of a 7-11. (sigh) "Yes, I turned up your guitar for your solo. You rock, dude." If that monkey on the drums keeps smashing that crash cymbal like that I'm going to shove it down his throat. My head is pounding. I don't know how much longer I can keep doing this. (sigh) It's only been 10 minutes. Did that bassist just fall off the stage? Maybe it's not too late to go back to filing papers at the insurance agency. Oh, good. the drummer found his cowbell. That will be the next thing I cram down his gullet. I work with morons.

This should be hilarious but for me it's just dejavu.  While sound checking the support band at this years bike club rally I actually had to point to the drums I wanted the drummer to hit because he didn't know the difference between a rack tom and a floor tom !!!
 
I guess they all end up on the floor eventually.

You've no doubt heard about the accordion player who left his instrument in the back seat with the doors unlocked, and came back to his car to find two accordions on the seat.
 
We've also left out bagpipes and digeridoos. They're great to jam with because, like drummers and bapu, you don't have to ask them what key they want to play in. 
 
 

Karyn, I thought those comments about the engineer might hit a little too close to home. Sorry for triggering any bad memories or PTSD. Also, there's no need for the drummer to know the difference between his toms when they are all tuned the same. (I can't stand it when drummers don't know how to tune their own drums. The thing between the ears has some data storage and processing capability. Try using it for something other than a spare woodblock for a change.)
 
Whether someone is an audio tech, musician, or plays bagpipes, there's no excuse for acting as though they are superior to everyone else. The best musicians I've known have also been the most humble. 

Not 'close to home',  it's more a case of it would be funny if it wasn't true...  We all make fun of musicians and drummers, but when the jokes turn out to be true?
 
It's still funny.

A guy I used to know played keys in a local Chicago jazz fusion band in the early 80's. Their band featured a juggler who, quite literally, juggled objects on stage throughout their entire set. The band was called Juggular and they stood out from all of the other acts. I believe their debut CD from 1980 is still available at CD Baby. (No, I'm not affiliated with the band in any way.)
 
Anyway, I thought of this juggler as I contemplated other "overlooked musicians" who could be mentioned in this thread. (The jugglar was also a percussionist, so the use of the word musician within quotation marks is valid.)
 
The band was remarkable to watch live even though they never made the leap from local band to national touring act. I don't know why I'm rambling about them now other than to give a nod to those unusual acts which stood out in some way.
 
 

Bubba likes clowns and jugglers.....
