Just don't attempt to do any fretwork and solder electronics while you are "in the grip" of some drink!
I saw SRV live many, many times. The first time, was in a tiny gymnasium at Montclair State College New Jersey, 1986 Year of our Lord. I was so close, that my hands where resting on the foot of the stage, looking directly up at him. I will never forget those yells (AHHHH!) during rests, right before he dug into the strings. Added bonus was seeing his eyes roll back in his head when he did this.
