I know very little (really nothing) about dance, but I did know the name Jacques d'Amboise, and I knew he was a dance titan. If you're a Broadway nerd like yours truly, you know that d'Amboise was also the dad of Charlotte d'Amboise (Cassie in the major "Chorus Line" revival a few years ago), and that d'Amboise was the father-in-law of Terrence Mann. How strange is the world? Terrence Mann had the rare honor of originating a role in a Sondheim show--"Assassins"--and this isn't even highlighted in his Wikipedia bio. Mann was the first Czolgosz; no one played this role before him, at Playwrights Horizons. In any case, a salute to Jacques d'Amboise today, and to his "four double tours" and "double cabrioles," in the film version of "Carousel": https://www.pointemagazine.com/jacques-damboise-carousel-2565577952.html Obsessed!
