A couple of jewels

New York City Ballet has announced a new seminar as part of its Discovery Programs for the 2006--2007 winter season: "A Tribute to Melissa Hayden" will be presented December 4 at 6pm at the New York State Theater. Jacques d'Amboise moderates the panel,
which features Francis Mason, Suki Schorer, and Hayden's former students Gillian Murphy and Megan LeCrone. Call 212-870-4074 for more information. As for the other gem? Sterling Hyltin (see photo), a most glorious wisp of a dancer, makes her debut as the Sugarplum Fairy December 9 at 2pm. It's a good cast all-around: Andrew Veyette is the Cavalier and Tiler Peck is Dewdrop.
