Thanks for the concert update, BillyBuzzy. I love PP&M, and used to see them every summer when they toured in the '90s. They didn't get to our area this year, but perhaps next.
I didn't know that Mary needed oxygen to sing. But, I'm glad that's an option for her that's working out, as I know that singing brings her great joy. She has such a wonderful voice.
Did they still do the solo performances midway through the show? I remember how Mary used to bring enormous photos of her granddaughter on stage to show us all how she was growing.
