During Mutual Radio broadcast of "The Adventures of Superman", starting in 1945 Superman and Batman, years before their comic book collaborations, really became a functioning team. But largely the team-up of Batman, and Superman provided some time off for an overworked Bud Collyer (Superman). These episodes called for Superman to be occupied elsewhere, and the crime fighting would be handled by Batman. Stacy Harris played Batman in this first team-up with the Man of Steel, and Ronald Liss was Robin. Batman and Robin returned several times over the years, usually with Matt Crowley as Batman and Ronald Liss always played Robin. Now,listen to Batman on the Radio and Movie Serials from the 1940's.
