Want to work on one of Sir Paul McCartney’s productions? Leave your hamburgers at home. Sir Paul has told his staff members who were setting up for his August 14 concert that they must emulate his strict vegan diet for one week. And it’s not easy work. Constructing the stage on its own required 30 hours. But the kitchen at the concert locale has sought to come up with tasty meals to help the crew members go vegan throughout the week-long work period. “Obviously there’s a few jokes flying around about ordering pizza, that kind of thing,” said Evraz Place Vice President, Neil Donnelly. “But for the most part, they’ve been fairly happy with the meals that have been provided.”
