Bill was the announcer for the series, and also appeared on-camera as King's assistant.  Some sources even refer to him as co-host.  The series was based on a radio program that premiered in 1945.  John Reed King was the host of that series as well, also with Bill's assistance.    

For most of its brief run, Bill was working this early series at the same time he was doing Winner Take All on NBC.  This pattern of being involved with more than one series at the same time became a constant in his career.  Some sources refer to this program as Bill's first appearance on network TV, but most indicate that he debuted on Winner Take All a month earlier.
