All excellent stuff....one other piece of advice....
Beware of low ceilings
I played a gig at one small venue and forgot how low the ceiling was (the higher than usual stage didnt help). Mid guitar riff, I jump in the air, only to smack my head off a light fitting (breaking the bulb and fitting). Much laughter, then applause as I kept playing with blood running down my face!
I was always more careful of obstacles and fixtures after that!
