Your umbrella wouldn't stand a chance out in that Bill! Better to just stay inside and play guitar (amps are great, but just playing is fun enough even without power). ?
Oh yeah, always a good idea to float the request/idea on a musician forum (this and others). I've been on several where spontaneous collaborations happen. There's quite a few players on here who could provide exactly what you're asking for.
Heh, I was referring to that famous blow-up when some girl on the plane pours ice water on him and he explodes irrationally yelling (among lots of expletives and threats) "I'm going to release the f-ing fury!!!"
Warning - Expletives galore!
