As the show was produced at the ATV studios in Elstree, England, Jim Henson and his Muppet production team bypassed Douglass's familiar laughs. New laughs, chuckles and applause were recorded for the first few episodes so they sounded fresh and new. Some of these laughs were provided by the actual cast and crew members reacting to dailies of episodes; eventually, "The Muppet Show" began recycling these same chuckles for later shows, establishing its own one-of-a-kind laugh track. A by-product of this convincing laugh track was the belief by viewers that "The Muppet Show" was indeed taped in front of a live audience, some even asking for tickets to attend tapings; Henson's son, Brian, noted how strange he thought it was that people believed the show was shot before a live audience. Henson himself knew that having a live audience was impractical, given the production complexities (the NBC sitcom "ALF" was also difficult to produce and utilized only a laugh track); he also notes that because of the series' vaudeville inspiration, having sounds of laughter was a necessity, but admits that it was not an easy task – "I look at some of the early shows, I'm really embarrassed by them. The sweetening got better later on, but it's always a difficult thing to do well, and to create the reality of the audience laughing." Henson himself initially felt apprehensive about adding a laugh track to a Muppet series, and later commented about the pilot episode not having a laugh track, saying "I did one special dry – without any laugh track – looked at it, and then tried it adding a laugh track to it, and it's unfortunate, but it makes the show funnier."
