OP here. Many thanks, as always, for the generous help.

I have thought for a while about a voice coach. I have recorded myself singing and find that my pitch is pretty good. But my voice sounds unstable. And I am sure that gets worse at a jam session, when there is no mike, and I am consciously or not pushing my voice beyond its limits. Funny, but people often comment on the deep resonance of my speaking voice - I get "you have a [public] radio voice," a lot. Clients have told me that they enjoy listening to my voice over the phone. No one has ever told me they enjoy my singing voice....

One good thing is that, even at this early and untrained stage, I have no issue at all singing while playing. In fact, I find that I do both better when I do both simultaneously. I do find it interesting when someone says that is a challenge. At least one hurdle I do not have to overcome.

Glenn, I have listened to several of your excellent videos. Funny, but I would not have pegged you as a bass. Seemed to me that you were an octave or so above that.

As some have mentioned, and it is concerning, you can dp damage to your vocal chords by inadvertently mistreating them. Got to get me a coach...
Thanks again, all.
