So I had a big band gig tonite...it's in my book and on my calendar for 4-6pm. For some reason I've had it in my head all week that it was 6-8pm. Has anyone else ever gotten fixated like that and just completely blown it? Fortunately, as I was going downstairs to print out a map, I noticed the correct time for the gig (this was at about 3:45) so I minimized the damage by showing up about five tunes into the first set. The bass trombone player was covering my part. The mind is a terrible thing to waste!!!
