"The Velvet Fog", caused other Mouseketeers to call Lonnie "The Velvet Smog". Lonnie appeared in more than 200 episodes of the original Mickey Mouse Club. The popularity he and other Red Team members enjoyed continued after ABC cancelled the series in 1959, as it was rerun in the 1960s and 1970s, then continued on the Disney Channel from the 1980s through the early 2000s. The "Mice", as the adult Mouseketeers often call themselves, continued to acquire new fans; eventually adults who were fans as children watched with their own children and grandchildren.
