Cue the fireflies. After netting ten Tony nominations, “Maybe Happy Ending” walked away from this year’s awards ceremony with six trophies including Best Musical and Best Leading Actor in a Musical for Darren Criss.

Broadway’s best musical winner had to delay its opening last fall and was selling poorly. But strong word-of-mouth and reviews helped this quirky show triumph.

Attendees, including Ben Stiller, Lizzy McAlpine, Milo Manheim, Christian Siriano and Daniel Dae Kim, danced to a funk band underneath an oversize disco ball.

Nicole Scherzinger, Cole Escola and Sarah Snook were first-time winners, while the original cast of “Hamilton” reunited for a performance.

Buena Vista Social Club,” “Maybe Happy Ending” and “Stranger Things: The First Shadow” built up early heads of steam at the Tony Awards — well before Sunday's main event even started. Each had a leading three trophies from the pre-show.
