I would say the lead vocal that best describes the center of my vocal range might be Feel Like A Stranger. More of a Bobby range.
Mississippi Halfstep is noteably closer to the top of my range.
The line, Last Fair Deal in the Country, is high for me.
But I sing 98% of the songs in our group.
So, for vocal purposes, I play with a Trio (I also like a Trio format for ease of volume control and overall musicality), and the bass player and I
tune down a half-step.
A half-step doesn't sound like much musically, but physically it really takes alot of pressure off of my vocal chords, and drops pretty much every Jerry tune into my vocal comfort zone.
Sometimes I just lower the key. Songs like Tore Up or How Sweet It Is play out just as good in A as in C, and I can sing 'em better in A.
Work up Mis-Halfstep in Em. That makes it much easier to sing and it still lays out nicely on guitar.
I do a fair amount of CCR tunes, and he is a true Tenor. Y'ouch! I have to drop Born On the Bayou down from E7 to C7... again, it still plays out nicely on guitar.
I used to do a fair amount of Bob Segar tunes in the 80's. Another Tenor. Sunspot Baby was a big hit for me back in the day

.
Keyboard players usually make a face when I say the rest of us are tuned down a half- step. With any luck they can just push the button that turns their whole keyboard down a half-step. Not sure if they can do that on a Rhoads or B3, though.
I filled in for the Jerry guy in The Garcia Birthday Band last Sat night and sang about half the songs on a 9-midnight gig at concert pitch.
I can muster up a pretty good head of steam at a live gig when I have to.
I don't see a need to blow my voice out at non-gig jams or rehearsals though, so I/we tune down a To0daLo0.
