Charlie Haden

When you listen to a symphony orchestra, and the basses don't - there's no bass part, there's not that much depth. That's why I'm attracted to the instrument, the bass. It brings depth. It's like playing in a rainforest.

I wanted to do 'Oh Shenandoah' because that's the town I was born in - as a tribute to my mom and dad for giving me all this music. I don't really sing this as a singer, because I'm not a singer. But I wanted to do it for them.

In L.A., I played with Joe Pass and Gabor Szabo. Mick Goodrick plays guitar in the Liberation Music Orchestra, and he's a real special player. Then I did a duet concert with Jim Hall at the 1990 Montreal Festival.

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.

What cracks me up is people who think I don't take baseball seriously. It's the most important thing in my life. They don't know how hard it is for me to get a bad game out of my mind. I still can't, but I'm getting better.
