Proving once again that old is gold, the Rolling Stones kicked off their 60th anniversary tour earlier this month in Madrid with Mick Jagger, Keith Richards and Ronnie Wood up front. At the same time, Paul McCartney and Ringo Starr are both on solo summer tours of the U.S. right now, including a Ringo concert at Tanglewood June 17th. So this week, in honor of our tenacious and indefatigable rock gods, I’ll give you a piece of a trivia about the groups, and you tell me if it applies to The Beatles, The Rolling Stones, or both.
