Actor Larry Hagman was so popular in American pop culture as the villainous 'J.R. Ewing' on television's 'Dallas' that when the character suffered a gunshot from a mystery character, the nation asked (with a little help from the promotions department) "Who Shot J.R.?"; which quickly became an iconic phrase. So massive was the fad, a song was recorded in honor of the phenomenon.
Of course, Hagman had other roles in a long Hollywood career; notably, the popular sitcom 'I Dream of Jeanie' and films 'Failsafe', Mother, Jugs & Speed, and Blake Edwards' Hollywood spoof 'S.O.B.'. His mother was the fabulous Mary Martin; most known for her role as Peter Pan on stage.
Larry Hagman played another role in rock n roll folklore ...
