My hero has always been the boss himself Bruce Springsteen. That would be mu obvious answer i have been in his presence and gave him a nod and been backstage with him and the E street band whilst he was waiting to go on stage at wembley arena and whilst they came back off to quench there thirsts before going back on for there encore.( yes i was doing security) but at least i had the privelage of guarding Bruce and the band. After the show started i swopped places with someone else and saw the show too. All because i could not get a ticket for the show. Through doing Security i managed to meet or be in the presence of some brilliant(& some very mediocre)people. Mohammed Ali was along with Bruce the greatest honour.
So if i could meet 1 person alive then it would be Bruce my hero.
If it could be anyone from History though it would be Elvis and i would try and knock some sense into him and tell him to lose that Leech Tom Parker and stay off precription drugs and Deep fried banana and peanutbutter sanwhiches.
Or John Lennon and tell him that if someone called Mark Chapman tries to talk to him outside his New York hotel to run like the wind screaming as loud as he can.
