I’m placing my votes for Eric Burdon & Timmy Taylor.

Richard Barr

No showmanship like that of Ian Anderson, from Jethro Tull

@MarvinLapsus - good call, but Freddie Mercury has to be a serious contender!

Jim Morrison (The Doors)

Your choice of avatar did nothing to give away your thoughts on the topic. \\m/

I´m split btween Bruce Dickinson (Iron Maiden) and Ronnie James Dio (DIO, Black Sabbath, Heaven & Hell), but outside the “metal” world I´ll sign for Freddy Mercury.

@Wulfensteinsson : I also thought about good ol’ Bruce, but I found him somewhat overwhelming! (I have always been a bigger Steve Harris fan).

Ozzy Osbourne- Can’t understand when he talks but he sure can wail out some tunes, I like his charisma and energy on stage;always jumping around and playing air guitar with Tony Iommi. These guys gave birth to heavy metal. https://www.youtube.com/watch?v=clySTJtd81c

for a laugh… David St. Hubbins - SPINAL TAP, and before that, The Thamesmen (as seen here) …and check out John “Stumpy” Pepys on the drums. He is the most relaxed laid back drummer ever. John Bonhams complete opposite. lol …and yes, I know that the two above mentioned band members are actors Michael McKean and Ed Begley, Jr. Liam Gallagher of Oasis has stated that his brother, Noel, thought Spinal Tap was a real band and the movie a real documentary. Too funny. :))

I really like Maynard James Keenan of TOOL & A perfect Circle. Maybe not the most profilic frontman, but his voice, style & technique is really fantastic. https://www.youtube.com/watch?v=u9MAg9E5K3w

Lee Brilleaux from Dr Feelgood, stalking the stage like an angry club doorman, completely self-assured, and Roger Chapman from Family (and later solo), just ‘into it’ - beware flying bits of tambourine and mic stand… http://youtu.be/BnUlfSMP9kY https://www.youtube.com/watch?v=L4bqMUSV6lQ Oh… and me! B-) https://www.youtube.com/watch?v=qdkZu0H2Yss Just an old show off, really… :))

either james hetfield from metallica or dan auerbach from the black keys

I’m going to have to vote for Maynard from Tool as well… I have a feeling that in years to come people are going to look at Tool the same way they look at bands that are on a whole different level, like Pink Floyd or Led Zeppelin. Honorable Mention goes to… Cristina Scabbia from Lacuna Coil Michael Poulsen from Volbeat and Benjamin Burnley from Breaking Benjamin

Pufnsnuff, Lee Brilleaux is my close second. I had the pleasure of his company on 2 occasions, once on a very decadent night in Amsterdam and the second drinking champagne in a nightclub in of all places Dundee, Scotland. A real gent and a great loss to music.

I liked the way that because he paid for his house with the money he made from music, he named it The Proceeds. Proper chap.

Ian Gillan

Kid rock.

Gary Cherone (Extreme). Saw them twice, Pornograffiti tour and Three Sides tour. Excellent both times. I do regret the fact that I never got to see Freddie Mercury live

Have to go with Glenn Danzig. Misfits, Samhain and Danzig changed my youth. However, Freddy Mercury, Bruce Dickinson, Phil Anselmo, James Hetfield are all in the same vane. There’s just no way for me to name a best, but I’m covered in misfits, Hatebreed and one old Mettalica tat so I lean more punk/hardcore I suppose.

Some other names worth a mention.   I couldn’t pick just one, there are too many talented folks.
