Follow the link below for a short video of Cher dancing with the Jackson 5 on The Cher Show; and below that is audio of Cher talking about the experience.
I notice on these commentaries (from The Sonny & Cher Comedy Hour, for example), her initial memories go right to the clothes she was wearing or some aspect of putting together the outfit. I think this is why she would be a breathtaking judge on Project Runway. And likewise here, Cher remembers Bob Mackie telling her she was getting too thin. She also remembers how challenging it was for her to learn the J5 moves (it took her all day) but how fun it was to work with so many people on those variety shows.
What the devil is that fellow doing in the foreground?
