Here's a report about Knorr by the late William Cetnar, former bethelite:
The late Bill Cetnar, who was a PFO (Personal Freedom Outreach) director, told of an incident that occurred in the 1950s while he was a Jehovah's Witness at Bethel, the organization's headquarters in Brooklyn. Cetnar told of how he, along with a couple others from the Bethel staff, were in an automobile with Watchtower president Nathan H. Knorr. Knorr was hushing Cetnar and the other occupants as he tried to find the broadcast of Billy Graham on the car's radio. Graham was in New York for a crusade at Yankee Stadium.
Why was Knorr frantically trying to locate Graham on the car radio? Was it to find out what message was being proclaimed by one of the more popular vanguards of "Babylon the Great?" No, nothing that profound. Knorr, Cetnar said, was trying to find out how many were attending Graham's meeting. It seems Knorr was consumed with the ambition to address a larger audience when he spoke at Yankee Stadium, where the Watchtower would host one of its international conventions.
