I keep going to the Game Show Channel to see if they will ever rebroadcast some of the newer, syndicated  "What's My Line" shows from the 1970's when I appeared on one of their airings. I just happened to catch the very end of a show from 1956 which identified the mystery guest as Gary Crosby. The show was over except for the signing off. As John Daly and each of the panelists said goodnight, Bennet Cerf, the last to speak, said he thought that Gary Crosby sounded more like Billy Daniels than his famous father. Does anyone know what the conversation was after the panelists had guessed, or had Gary Crosby's identity revealed to them?
