I attended many TV shows in New York as a child, including talk shows and game shows. But the most unique show that I saw as a member of the studio audience was "That's Life". I saw the taping of several episodes, including the first one, if memory serves. There was also an episode that featured Terry Thomas, who, like Morse, had a gap in his teeth. The two made light of the fact that they shared this trait, and even sang a song about it. There were edits, and sometimes the sessions were very long, but for the most part, it was "live to tape". There was even a studio orchestra. It was a fun show to watch from the theater. They changed the location after a while, and like most TV shows, "over distributed" tickets, and it was hard to get a seat. I think it also had become a "hot ticket" in New York, in that it was very much like a Broadway show, and it was free! I would love to see these episodes again. I wonder if the tapes still exist.
