The most trusted man in America, CBS anchor Walter Cronkite, happened to be off, and Roger Mudd was sitting in. The newscast's 'fish bowl' - the key group of senior producers - had decided to lead with a story about the proposed Panama Canal treaty. While the program was being prepped, the wires exploded with news that Elvis Presley had died. ABC and NBC led with the death and ran special broadcasts after their late local news. CBS producers decided to include it, but only later in the broadcast.
