I used to be a tenor, now a solid baritone. Also lost a bit of pitch control but that seems to be getting better so there is some hope. Honestly, I wasn't that great to begin with. I have encouraged my musician friends to record what they have written now. I had several songs in the works that I wish I had recorded BC.
