Just for context: "Super Circus" was an early TV Circus done Live in Chicago and fed over the ABC network from WENR (WLS); and "The Big Top" was done Live in Philadelphia and fed to the CBS network from WCAU. Both ran in the early 1950s. Although I hadn't been born, I collect old TV Guides. Both shows also used live animals including elephants and tigers.
The video is likely from early part of 1981. The team members at that time were TIna, John, Bobby, Jodie, micheal, Joey and Nicole - exactly the people featured in this video. 1980 saw the departure of Karen Knowles and Stephen Zammit Micheal didnt join until 1981, and Nicole left in 1981, so I think the error has been made in the title dating. None the less it was still really enjoyable to watch as there are very few 1981 YTT videos online. Just wish there were more.
