Okay, a more accurate title would be "minimum prep time". Post your gigs that you had next to no time to learn material for, get set up, etc. Yesterday the regular bassist for out school pep band was out, so I asked the band director if he wanted me to fill in. I'm normally a tuba player, but I figured that if I duplicated the tuba parts it would be close enough. He was a little hesitant but told me to go get my gear and start practicing. I dashed home, grabbed my stuff, dashed back, and spent an hour learning stuff. He told me "Okay, you're on. Keep practicing." After a brief break to haul everything down to the stadium (if this was an away game I probably wouldn't have bothered), the guitarist and I turned to low volume and I kept working through everything some more. Whenever the band wasn't playing I turned down my bass volume and kept practicing. Some songs sounded like utter crap, but when we started playing something that I knew, it worked really well. I talked to the director later and he thanked me for my effort and said I did a good job for the time I had. It was nice to spend a night with my true love instead of her brass counterpart.
