tina fey tracy morgan jane krakowski '30 Rock' series finale production wrapped with Tracy Morgan singing songs from 'Thriller'Hours after wrapping “30 Rock” Tina Fey tells Zap2it it was a thriller — or at least its behind-the-scenes soundtrack was.

Fey and the rest of the cast, save Alec Baldwin who had finished earlier in the week, wrapped shooting “30 Rock” Wednesday (Dec. 19) night. And as had happened during all of the 134 episodes, Tracy Morgan cracked her up with his renditions of Michael Jackson songs.

“Last night there was a delay and as happens every time in seven years it ended up with Tracy singing songs from ‘Thriller,'” Fey says. “It was the same three Michael Jackson songs so many times. Last night, it turned into an impromptu break dance party.”

For the record, Fey did not break dance ,.. or moonwalk.

She did, however, “take my turn on the dance floor,” she says. ” I was more poppin’ and lockin’.”

The series finale of “30 Rock” airs on Thursday, Jan. 31 on NBC. Fey, the star and creator of the Emmy-winning comedy — who chose to end the series after its seventh year — is already moving onto her next project, hosting The Golden Globes with her pal, Amy Poehler on Sunday, Jan. 13.
