An excuse I hadn't heard before

Chattanooga man causes disturbance at local Guitar Center, says he is "too high" to play quietly

"The report fails to mention whether the man played Smoke On The Water, or if he gave an indication of what he was "too high" on."

Talk about a lasting cultural impact.

weird, I'd be more likely to play quieter if high due to akwardness.  Drunk, sure; crank'r every time.
