It feels very loose, in a good way. There's a very large comfort level with the band because we've been doing it for a while now. There's just a lot of trust between everybody.

It's great. It's supercool. He's got a lot of energy, it's mind-blowing. I think he's just gifted. God sort of said, 'I'm going to throw about 50 people's talents into this one person.' He's just blessed with a lot of things.

It's been going really well,

Backstage I met Pete Townshend, Roger Daltrey, all these people, even (former President) Bill Clinton, ... It was way too much to take in in one day.

You get used to anything - good or bad - and that's the good thing. I mean, if we have a problem we're able to talk it out.

I knew he had three days before he had to return to England and I just said 'Hey, Paul, wanna play on a tune?' and he agreed. Everyone from (McCartney's) touring band came in and we did the song together - it was very surreal.
