"I didn’t know it at the time, but David Lee Roth had patterned himself after Jim “Dandy” Mangrum of Black Oak Arkansas."
That shouldn't have taken longer than 10 seconds. When I first saw DLR, I thought it was a bad pic of Jim Dandy.
His (not really singing) voice sounded like Jim Dandy's too - though that is doing the latter injustice because he was never as off-key.
I believe every word. Getting DLR's vocals down must have been cut and paste, word for word, tone for tone. He was tone-deaf and still is. I don't think it's intentional or negligent, but a real disability, just like some people are innumerate.

Call me old-fashioned, but especially with a hard rock or heavy metal outfit, I expect the lead vocalist to be top notch - think of Rob Halford or Steven Tyler. If you have to scream above the melee, friggin' do it right and in tune! DLR's hisses, catwhistles, falsetto shrieks and yelps never sounded in tune to me, even on record. I always wondered
"Am I the only one hearing this, what's wrong with me?" 
Venn in Tshörmanny vee vhissle, vee dö it richtig, jawohl!
Even Udo, no Caruso himself, was more on target, but then wearing camouflage must help with that!
