I have played the circus many times and have to say it is truly a gig from hell! Yes, it was a gig that helped to pay the bills, but there wasn't much that was fun about it. Pretty much nonstop playing with barely enough time to turn pages. The worst thing is that after playing like 10 shows over the course of a week the music sticks in your head.
Once I was a little too close to an elephant that apparently had some kind of explosive diarrhea. It wasn't pretty.
The circus is one of those gigs that seems to always come at a time when you need the money, but it is also one of those gigs you hope you don't have to do too many times in your lifetime. Much more fun to go as a spectator.
Plus, clowns are kind of creepy.
