Late 70s, early 80s colour documentary film about pole dancers

I only caught this once on tv. It’s not, as far as I am aware, a Nick Broomfield documentary, although similar in style. Colour documentary film, set in the U.S. interviewing pole dancers, lots of leotards and disco. I remember it because the model Gia (Cindy Crawford was named ‘Baby G’ when she appeared on the scene for Gia Carangi) appeared in one scene of the film dancing down the stage cat walk and hitting a pole. Think Channel 4 in the U.K. may have aired it once, which is when I saw it.
