We had one harmonica player that showed up at EVERY cotton-pickin' gig and wanted to play between sets. The guy stank up the joint (literally AND figuratively.) We tried to be kind but finally had to eschew subtlety to get the guy to shove off.

Have you ever heard an EXTENDED version of The Hurricane (Dylan) done by someone who THINKS they know how to play the harmonica? Ergh. I'm gettin' hives just thinking about it again.
