well, actually not me... although I did meet a few....
My sister has been a dance instructor her entire life.... she's met most of the most famous choreographers. She met Bobbie Burgess, (Mouseketeer and that dancer on Lawrence Welk)... still knows him, actually, but not well.
Her favorite choreographer she ever worked with was Gwen Verdon. She was an actress.. but at heart a dancer.
Dancers... I know this having been around them my entire life... they are every bit as athletic and the greatest athletes around, more so, actually. - JamesJM
