John Charles Daly
Daly's first foray into television was as a panelist on the game show "Celebrity Time". This led to a job in 1950 as the host and moderator on a new panel show produced by Goodson–Todman, "What's My Line?" The show lasted 17 years with Daly hosting all but four episodes of the weekly series.
Colin Mochrie
After the British version of the show ended its run, Mochrie joined the American version of "Whose Line?" hosted by Drew Carey on ABC. He was brought on alongside Ryan Stiles, who was also a regular member of the UK cast. Mochrie appeared on every episode from its debut in August 1998 to its finale in 2006. He noted his favourite games as "Scenes From a Hat", where he would have to act out scenes based on suggestions by audience members, and "Whose Line" where he and Stiles would act out a scene and have to add in lines written on pieces of paper. He felt that his weak spots were the musical segments and the "Hoedown" game, which he said was the only time during the show when he felt total fear. Mochrie, who cannot sing, usually spoke his lines instead of singing them.
