Entertainment historians from across the country gathered Sunday on a field near Hollywood to recreate the original 1976 Battle of the Network Stars. 'We dedicate our re-enactment to the brave souls who fought it,' said Network TV Historical Society co-founder and insurance-claims adjuster Drew Kamen, who played the part of CBS team wiseacre Jimmie Walker in this weekend's event. 'Let us never forget the pivotal foot race between CBS's Robert Conrad and ABC's Gabe Kaplan.' Kamen, like the other re-enactors, wore exact replicas of the striped tube socks and nylon running shorts used in the original battle.
