Mahalia Jackson

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.

Corinne Bailey Rae I listen to a lot, and I'll hear Desert Island Discs and quickly write down the name of a song, and it will open up a new area of music for me. I discovered an Argentinian guitarist, Jose Luis Bieito, on Classic FM.
