Singer says he skips the drinks and goes for light snacks such as raisins

Former Beatles star Paul McCartney says he has stopped drinking alcohol before performing.
Asked if he enjoys a drink to calm his nerves prior to gigs, McCartney said: “No. I used to try that, particularly in the early days of Wings when we would tour. But it didn’t work. I would just forget the lyrics.”
The music legend says he relies on healthier snacks to prepare for a concert.
“I don’t eat or drink before I go on because I sort of like to feel light. Then afterwards I can get heavy and have a drink. But before I go on I don’t do that. I do have little sort of snacky things in the dressing room that I might just grab like chocolate covered raisins and equal amounts of salted cashews,” he said.
