Singing really oxygenates your blood. You stretch your lungs and take in much more air into them than before. It's really good for your health.
We would also go to musicals. So Singing In the Rain, On the Town, and West Side Story. Especially West Side Story because played that a lot before VCRs, so that would be something that would be a big deal if it came on, you caught it. So that really started, my family was not in show business at all but really loved that kind of thing.
I grew up on musicals, and I know they are quite the thing now, but I'm actually a little indignant, because I started taking singing lessons years ago - I put the time in!
