Hah! I thought at first that it read, "the SWEETEST gig of my life"
, and did a double-take...
I used to have quite a problem with my hands sweating PROFUSELY when I played in any setting remotely considerable as a "gig". To the point of making it difficult to play, it was as if a faucet was turned on. It was, for me, a stage-fright/nervous reaction sort of thing. Somehow, I can't even explain exactly how, I managed to psychosomatically turn it off.
I really can't clearly remember what 'n' how, it's as if I made a secret pact with myself, locked it up in a hidden file-cabinet, and threw away the key!
Now, I'm glad to say, if I sweat, it's all-over and due only to heat and humidity! I would've been it the same boat you were had I been there.
