Tommy Cash and I did a show in Rhode Island. Imagine my shock when he called me out on stage to sing a duet with him. We hadn't rehearsed anything! In a panic-stricken stage whisper I asked, "What song are we singing?" Without telling me the song, he said, "Don't worry, you'll do fine." And then he sang out to the audience "Daddy sang bass" and I chimed right in, "Mama sang tenor."
