My mom was a hell of a singer, soprano, though she was too tremulously shy to solo even in the church choir, but could really belt it out around home. "Now the day is over/ Night is coming nigh/ Shadows of the evening/ Fall across the sky." So she's one of my favorites too. Although my late wife didn't sing, I'd occasionally catch her doing a pretty good song in an elfin voice very different from her rich alto speaking voice, ideal for her teaching role. My wife now sings enthusiastically at every opportunity and isn't too good to let me chime in. We're not prime time, but full throttle. She was a church pianist as a young adult. So there're three of my favorite female vocalists. No agents, no ASCAP, no venues, no problem.
