here's a hint..this clip is from the 70's and that's what he look like, but i can't go back in time to see him for another clue as i might accidentally bump to my other self.
Phil Collins? George W. Bush? Barrack Obama? Julia Gillard? Queen Elizabeth II? Humphrey Bogart? Brad Pitt? Ian Thorpe? John Lennon? Frank Sinatra? Arnold Schwarzenegger? King Henry VIII?
I'm not sure whether you picked it up or not but I'm stumped.
