There’s a beauty shop, a 5K race, even a health and wellness tent where you can take yoga classes.This is what Bonnaroo has become in its 12th year in Manchester.This year will feature – among the biggest legends in music – Paul McCartney as the Bonnaroo headliner.“He’s definitely royalty,” said Bonnaroo co-founder Ashley Capps of AC Entertainment.Added co-founder Rick Farman of Superfly Productions, “He’s the biggest name we’ve ever had.”McCartney anchors the Bonnaroo lineup with a performance Friday night at 9 p.m. Other major acts include Tom Petty and the Heartbreakers (Sunday at 9 p.m.), Mumford & Son (Saturday at 9:30 p.m.), ZZ Top ( Friday at 11:30 p.m.), and Billy Idol (Saturday at midnight).It turns out, McCartney is a deal that’s been years in the making.“The ball first got rolling during a trip to London in 2007,” said Capps. “To get a guy like McCartney, it’s one of those things where the stars and the moon have to align just right. Well here we are six years later and everything has fallen into place.”With more than a decade of experience, Bonnaroo is looking for ways to grow like never before.
