Sorry about cutting so much out, your post is actually great, long posts by people who give a damn what they're saying are the most interesting ones.
What struck me was that between those two core truths, strange paths can be traced.
Earlier I posted about a Stranglers bassline in front of a not-very-discerning audience. (I'm not a master of hyphens but I do try.
On one hand, the audience may not care, and judging by the poor sound they WERE very easily pleased. What was most interesting was that I'd told the guys running the pub and the live sound that I was intending to play folk tunes, maybe some Stranglers if if they thought it might work in that pub (seemed unlikely to me but I wanted to try it).They said yes, they were up for that, so I did it. Now, these guys are the ones most likely to have their expectations thwarted if I actually sucked, but they were the ones who liked it most.
Different context, it may well have fallen like a lead balloon, but in this case the failure of a sound device lead to the same tough conditions that Burnel had to cope with early in his time with the Stranglers, so maybe that's partly why it worked.
It could be said I should have had a backup device, or at least a power switch or soldering iron, but there's a limit to what I can carry alone, a limit to time available, and no matter what the context, or its scale, we can only use what we have. The way I see it, the show must go on, and it may need some change to fit circumstances. This is why I don't prepare a set list, instead I'll prepare stuff I can do in case the other stuff isn't going to work. It's not a plan B, it's actually the revocation of the notion of planning, it's tactics, not strategy, and it can save a show.
I knew if my gear failed I could rely on my playing. Without that it WOULD have failed.
