London's top theatrical honors were handed out April 14, and many of the nominated musicals performed during the annual ceremony. See the full list of winners here.

The top winner of the night was Jamie Lloyd's Broadway-bound, minimalist revival of Andrew Lloyd Webber's Sunset Boulevard, which took seven categories including Best Musical Revival. For their performance, the production brought Tom Francis (set to bring his now-Olivier-winning performance to Broadway) to sing the musical's title song, starting from outside Royal Albert Hall and traveling to the stage by the number's end, echoing the staging in the production. Watch above.

Fresh off its U.K. debut at the Donmar Warehouse, Tom Kitt and Brian Yorkey's Next to Normal was up for Best New Musical at this year's awards, along with a nod for Broadway favorite Caissie Levy for her performance as Diana. See the company perform a medley from the show below.

Best New Musical went to Operation Mincemeat, which tells the true story of a bizarre secret mission that helped the Allies win World War II. No spoilers, but the scheme involves a stolen, well-dressed corpse. See the company perform "Born to Lead" from the now-Olivier-winning musical below.

Also nominated for Best New Musical was The Little Big Things, a pop musical telling the story of artist Henry Fraser. The former athlete turned to visual art after becoming paralyzed from the shoulders down in an accident, with his work done by using a mouth stick attached to a paintbrush. A complete performance of the musical will stream via National Theatre At Home beginning next month, but watch the cast of the show perform a medley of the musical's title number and "The World Is Waiting" from the April 14 awards below.

Best New Musical nominee A Strange Loop didn't bring its London cast, but rather its Tony- and Pulitzer-winning author Michael R. Jackson, who performed "Memory Song" from his score, accompanying himself at the piano. Watch below.

From the Best Musical Revival category, the immersive Guys and Dolls brought Best Actress in a Musical nominee Marisha Wallace and her Hot Box girls to perform the show's "Take Back Your Mink." Watch below.

Also up for Best Musical Revival was the encore run of Hadestown. The company brought "Wait for Me" to the Oliviers. Watch below.

Stepping away from nominees, host Hannah Waddingham kicked off the evening with a jazzy take on Cole Porter's "Anything Goes." Watch below.

The evening technically kicked off with this rousing speech from Joseph Fiennes, which saw the actor bring his Olivier-nominated performance as England football manager Gareth Southgate in Dear England to the stage of the Royal Albert Hall to get the audience ready for the evening's festivities. Fiennes will reprise his performance in an upcoming limited series adaptation of the James Graham-penned play for the BBC. See Fiennes introduce the ceremony below.
