What do you say during a performance while tuning or while waiting for someone else to tune? I know there are some who can easily tell lengthy jokes and tune at the same time. I am not one. I can barely string three words together and tune my guitar at the same time. What I appreciate are those one-liners some use at such times, for instance, "It was in tune when I bought it!" or "I once knew a lad who thought fingerpicking was related to diabetic testing." Any thoughts or suggestions?
