We'll be getting there fairly early and the temp will probably be in the low 60 then, so it will be a gradual decline in temp., so no sudded shock. Plus I don't play trem guitars, so no problem there. I think my hands will be fine once we get started. This gig is going to be more like practicing infront of a bunch of people, so it's not technically a gig. But, I'm still treating it like it's a paying gig.....alway's wanna be my best
