Karen Magnussen of Canada - Olympic Silver Medalist and World Champion made this move very popular and in fact it was always a part of her programs as she was so good at it. Here is a video of her world championship program - 1973 - she elected to do a bauer into a flying sit spin in this program, but it is still fantastic. The footage is sort of grainy, but worth watching for the historic value.
