It happened at Peartrees on 49th St and 1st Ave. Peartrees was a watering hole for athletes, sports writers and personalities, among other assorted characters. I had worked there, but was no longer. The bartender, John "Shirts" Hughes, a friend of mine was notorious in the sports community. It was Sunday night after the games and after their show. I wasn't paying close attention but a heated discussion turned to shoving, which resulted in a punch. It ended quickly. Musberger left immediately, followed shortly thereafter by Jimmy "the Greek".
