On Friday, Grand Central Terminal celebrated its 100th birthday in classic Big Apple fashion: sensational performances attended by huge crowds of spectators.

Highlights of the all-day event included addresses by Cynthia Nixon, Billy Collins and legendary Mets player Keith Hernandez. Musical performances ranged from the West Point band to the Trans-Siberian Orchestra’s electric violinist Sarah Charness. And then of course the dancing: the Knicks City Dancers, Knicks City Kids and Keigwin + Company made appearances, as well as hundreds of young students from NYC’s Dancing Classrooms, a public school ballroom dance outreach program and subject of the 2005 documentary Mad Hot Ballroom.

Photographer Jason Lewis captured these images of students foxtrotting, rhumba-ing and waltzing across Grand Central’s main concourse floor, an opportunity few dancers can hope to experience:
