We play a lot of outdoor gigs. One of the festivals we play is always in the middle of July. Out of the past 9 years of playing that show, there have been several years where it was high 90's with the sun reflecting off of the metal stage. I've guzzled gatoraid and still gotten dehydrated causing my voice to tighten up, my fretting arm to cramp up.. and I remember one year I tilted my head back and held out the last note of a song, only to feel my knees buckle.
I looked over at the other guitar player and said... "You need to sing one... I need a sec.
