Went to see a mate's band last night. Four piece that included two full time musicians.
The guitarist (one of the two) breaks a top E. Finishes the number and announces a 5 min break as it's his only guitar. Second guitarist starts a number that he will sing to keep things going whilst the other searches his case, accessories bag, his jacket, other guitarist's case, bag of bits, his jacket, the bass player's case and bag only to find, there are no spare E strings. Finished the evening on a borrowed guitar. Nothing like being prepared is there??
