I don't drink or smoke or do drugs...been off them all for over 30 years. They became a major problem, so I quit.
I had played plenty of gigs under the influence, and I always thought it helped me play better...until, someone recorded the band one night...I was pretty awful.
Last year, at a dinner gig, one couple asked if they could buy me a drink, and I said, "No thanks, I'm allergic to alcohol."
"You are?"
"Yes," I said, "When I drink, I break out in spots!"
"You do?"
"Yes," I replied, very seriously, "Bars, legions, nightclubs, bootleggers, and occasionally, jail!"
