When we decided to go to Cuba to perform, we did it because we just wanted to build a bridge, you know, between Cuba and the rest of the community. And we just wanted to prove that music and art need to be over all ideology or way to think life, and we just wanted to go in there and play just because of love.

I don't collect the way other people do. Some people collect rare guitars, like, 'I have a '54 Strat worth $50,000.' And I don't collect the way Nash does. Nash has Duane Allman's guitar and Johnny Cash's guitar. I bought guitars because they sounded good. I played them, they sounded unbelievably good, and I couldn't resist.

Frankly, as much as I love to improvise, it hasn't been difficult to stick to the script on 'Mad Men.' The writing is so precise, and the story so carefully crafted, that I don't think there's room - or need - for ad libbing. I could never come up with dialogue as lovely as these writers do, anyway.
