I was part of a caper team made up of the guys I work with at Apple. We were also a UCSC singing group, performing chorales as a cover story. It was one of those work together/fuck each other over caper stories.
One of our performances, which was going to act as a cover to permit us to do a job, turned out to be the same night as the 35th anniversary of some big club venue-- the Fillmore or the Warfield or something?-- and so attendance for our show was very minimal. Then it started to rain; all the audience went and huddled in their cars and our program had to be cancelled. Patrick C. had prepped a solo piece for the program; he was really pissed that he didn't get to play it.
This, of course, threw all the timing off for our job. We had to scrap the whole caper. Afterwards, someone delivered a bag of old mail, forwarded from previous addresses. But it was all wet from the rain.
