In the mid 70's the musician's union (remember those?) sent me to fill in with a country band at a bar in Sioux Falls, South Dakota. That's right, jaywa, your town! I got there before the band did, and when they arrived I helped them load in and then took a look at the set list. Nothing too tough, lots of George Jones, Tammy Wynette, Loretta Lynn-type stuff. I was 19 and had long hair and a beard. The band consisted of two couples, and they were all in their late 30's to mid-40's and had well-oiled hair. I never did figure out who was married to who - it seemed to be kinda interchangeable.
They gave me a shirt they told me I had to wear. It was a size medium, so it was only 2 sizes too small. You get the picture: lots of oval-shaped gaps of skin showing between the buttons.
The band leader was kinda mean looking and gave me one instruction: "Now don't be playin' too jazzy."
No problem. It was country, and back then country wasn't anything like the MOR pop/soft rock like today's country. Just play the roots and fifths and walk up and down for the chord changes, right? Except every time I walked up to the IV or back to the I the band leader would shoot me the evil eye. And he must have told me five times "I told you not to play so jazzy!"
All four of these people drank a lot of Jack before, during, and between sets. We were gonna play four sets that night, and halfway through the third set one of the guys and one of the gals were so polluted they couldn't be understood when they sang, and they had to prop themselves up in order to remain reasonably vertical. The band leader announced "Now here's one for the young people" and we launched into the worst version of Proud Mary I have ever heard. No problem. I knew that bass line note for note just the way it was on the record. When it got to the point where the bass line walks up to the V, I played it that way, and the band leader stopped everybody mid-song.
Using generous doses of profanity on-mike, he fired me on the spot because "no one here wants to hear that hard rock crap". So they got their shirt back and I left. I had to file a grievance with the union in order to get paid.
Wow, was that fun!
