This hasn't happened to me in a while, and I'm having a rough time shaking it. Wanna know how you guys deal with this kind of stuff.... In my cover band last night I panicked and lost it completely. We do Flavor of the Week. We used to do it in drop D tuning, but a little more than a month a go started doing it in regular tuning. Didn't play it for a couple of weeks, forgot how I relearned it... and once the song started I was a gonner.... I panicked, and totally lost it for the about 30 seconds of the song. I was clueless - completely blanked out as if I never heard the song before in my life. Got it together with the help of my guitarist. I don't want this to ever happen again. If it ever does I think I'm gonna fake my bass goin dead or something.
