The one that always gets me is the performer who switches over to DADGAD for one song and then right back to conventional tuning for the next one. No matter how long he/she takes to do this, it never seems to faze them. The whole thing becomes part of the performance and can take as much as five minutes. Double that if they decide to talk in broken sentences through it all. Fortunately, I'm a smoker so I just bugger of for a while. Wouldn't 2 guitars speed things up a little? Ah well, it's all part of the game. I'm sure the good outweighs the bad or we wouldn't be there.
