This weekend one of my bands is playing at a medieval festival. We played at a different one at the same castle two months ago so more or less knew what to expect. We agree with the promotor that the first set we'll be playing in a big fallen willow tree. So the time comes, we're up in the tree, and then the PA announces that they don't know where the band is and are urgently looking for them. Several times, basically throwing us under the bus. We send one guy down the tree to find the announcer (who's on a wireless mic and wandering around) and tell him we are where we had agreed to be. The dozen or so people who had already gathered in front of the tree leave. That was pure Spinal Tap...
But that's not all. We get this straightened out, our messenger comes back, some more people show up, we play a few songs, then I see someone under the tree is talking to the band about something. I don't know what's going on, can't hear, can't see with some branches in the way, but I understand we have to get down from the tree and go elsewhere. Turned out it was a radio station which wanted to interview us, but their equipment didn't have range where we were playing and they were supposed to go on the air in five minutes so we had to walk about a hundred yards to the other side of the camp and just set up in the middle of the grass. Fine. So they're talking to us, some people gather, and they ask us to start playing a song. We start playing, play about one verse, then the radio people just up and leave. We finished the song anyway as there was a small crowd watching, but being abandoned in mid-song by the radio people was also sorta Spinal Tap.
As a bonus the next day we ended up playing two sets at the bottom of a moat. It wasn't maintained in centuries and is really just a broad shallow depression at this point, but still...
