Hi Greg
You know my voice, if a song's beyond my abilities I won't bother to learn it much less sing it.

It's a matter if you want accompaniment or not. Personnally when I sing I usually don't care, there are some/few exceptions. I don't ask for accompaniment but I don't frown on it either. So if I sing in a session anyone's welcome to play alog or not but I'll sing it in the key that I've learned it in because I put a lot of time, effort, energy & pratice in finding where I want to sing it & over time that key is where I'll start it (usually) & I'll stay with unless I'm off. If I need to stretch my vocal cords because I'm to low or to highThat's not doing me or the song any justice nor is it fair to the listener not to put it in the best place possible.

If you want accompaniment & you can ajust the songs' key & it fit for the musicians that's fine & that's a different matter, but the song should come first, always.
