Hard to choose between Bono and Mick Jagger. I went for Bono; somebody had to.
A little surprised that Freddie is running away with this thing. Perhaps I shouldn’t be.
Bon Scott.
My most favorite front man is Marty Roe of the country band Diamond Rio. 
God bless you and every member of the act always!!!

Freddy was the best I ever saw live, but I only saw 6 of your list live.
I once saw him strip off his vinyl pants, wearing nothing put high heels and a vinyl jockstrap. He then squeezed the sweat out of his pants into his mouth, then started moaning into the mic while humping the floor monitor…soooo…winner?
That’s what’s known in the Rock n Roll biz (and clinical psychology) as commitment!
I voted “Other”: Ian Anderson. How many other bands could be readily identified just by the silhouette of their frontman? And live, he’s funny as fuck.
I’ve seen, by my count, 18 of those listed. And still, the greatest front man I ever saw was Fred LeBlanc from Cowboy Mouth. He’s a sort little troll of a man, fat and kinda disgusting…
But he has more charisma that Bill Clinton crossed with Christ himself.
Queen.
Good point. Although “Queen silhouette” wasn’t a very good GIS like “Jethro Tull silhouette” was, “Freddie Mercury silhouette” certainly was.
