I got fitter when I did 'Joseph and the Amazing Technicolor Dreamcoat.' I wore a loincloth - that's a lot of motivation!
Actually music gave me the support when I needed it. I would never have gone to college unless I'd gotten a piano scholarship. And now I'm so glad I got to learn to play the cello which is a different experience you're flexing a different muscle but it's beautiful because it is music.
