The average age of the band members is 73 and they haven’t had a hit record in two decades. But the Rolling Stones are making more money on tour per night than any other live music act right now, according to Pollstar, a publication that tracks live events. The Stones grossed about $10 million per show on their recent 12-city, 14-show “No Filter” tour, selling approximately 63,000 tickets a night at an average price of about $159. That’s about $1.7 million more than current 2nd-place holders U2, who are grossing $8.2 million per show on their current tour.
