Lyrical Slayer
Gosh, this takes me back! I had a sequined boob tube just like those ones (but mine was just on the cusp of being out of fashion by the time I got it) and satin pants.
Interesting bit of film. Obviously the choice was have the dancers moving in time or the singing matching up with the lip movements. And they went with the dancers! Fortunately, there's so much movement anyway (and not so much of The Real Thing) that it doesn't detract. Nice to see members of Pan's People/Legs & Co moonlighting there!
