We'd love to be playing to five or six thousand.
Because I missed being with Prince on that [stadium ], and it's a lesson that sometimes you have to push yourself a little harder for your friends.
I watched R.E.M. connect with the back row of a 50,000-seat venue.
I was thinking of doing some exhibitions where I combine tennis and music. I might have a show at, say, the Staples Center, where I might play an exhibition against somebody who would be interesting, then take a break and go do a show.
I'll never forget the first concert I basically went to. Actually, Sonny and Cher was my first concert, but U2 was my first real concert. I was 17 and saw them at JFK Stadium and had really crappy seats.
I headline concert halls for 20,000 people, but I still play smaller venues.
My first stadium show was in China, it was a 50,000-seat stadium. I think 40,000 showed up.
I would love to play a show with Kanye West. That would be amazing. I want to play a show with Tom Petty or Bruce Springsteen. It would be really fun, especially to stick around, watch their show and watch how they work a crowd. It's really a wonderful thing.
