I don't AGREE with superstitious routines, but there are a couple of things I'll always do before PERFORMING. I'll get together with the band and chill out, and then, just before I GO on STAGE, I'll always CHECK my flies.
I'm not massively into the screamers, because I THINK sometimes fellas just hit it and there's an element of luck over whether it flies into the top corner or over the BAR.
