Well, I really can't blame him..

Your signature piece - considered a virtuoso piece at the time - is played by someone else right before you go on.. That took cajones...
But, if they treated Derringer like crap before that show, then I applaud him for doing it.. Derringer was a legend even back then - no need to treat him poorly..
