Sara Ramirez

The doctors of Grey's Anatomy are not finished singing.

Many of the ABC drama's cast gathered Sunday night at UCLA's Royce Hall to belt out tunes that were featured in last year's musical episode, "Song Beneath the Song." Although the episode was quite serious — a pregnant Callie (Sara Ramirez) flew through a car windshield and hallucinated her co-workers singing as they desperately tried to save her life —  Sunday's "The Songs Beneath the Show" event, benefitting the Actors Fund, was a lighthearted affair.

Sandra Oh and Eric Dane acted as emcees for the night, though Dane desperately wanted to join in on the action. Apparently, he can't sing a lick, but that didn't stop him from trying to jam out on a guitar and even slipping Grey's music supervisor Alexandra Patsavas his demo, which she promptly tossed.

Ramirez, Kevin McKidd and Chandra Wilson opened the show with Snow Patrol's "Chasing Cars," which was followed by renditions of Get Set Go's "Wait," Jesus Jackson's "Running on Sunshine" and The Fray's "How to Save a Life" sung by cast members Sarah Drew, Kim Raver, James Pickens Jr., Justin Chambers and a pregnant Jessica Capshaw. Chambers also brought out his three daughters to sing "Young Folks" from Peter, Bjorn & John, which was not featured in the musical episode.

Following a special performance by Ingrid Michaelson, Oh then asked the crowd if Grey's should do another musical. Though the rowdy crowd begged for more, the cast decided to read fan comments that both praised and panned the show's previous effort. The cast decided it would be a while before they'd try it again. "Maybe Season 13," they joked.

Grey's Anatomy airs Thursdays at 9/8c on ABC.
