Here's a little-known fact about celebrated New York City Ballet Principal Dancer Tiler Peck: She made her Broadway debut in 2001 in Susan Stroman's revival of The Music Man alongside Rebecca Luker. Over a decade later, Peck, Luker, and Stroman reunite in the new musical Little Dancer, at The Kennedy Center, where Peck plays Marie van Goethem, the young dancer who becomes a muse and source of inspiration for artist Edgar Degas. In this number from a recent rehearsal of the Ahrens and Flaherty musical, Peck shows off her skills not just as a dancer, but a triple threat. Here she is, with Kyle Harris, performing "Musicians and Dancers."
