‘Parks and Recreation’ Cast Sings Farewell With ‘Bye, Bye Little Sebastian’ on ‘Late Night’ (Video)

Aubrey Plaza and Jim O’Heir grossly make out the whole time

Late Night

What better way to say goodbye to NBC comedy “Parks and Recreation” than with a big musical tribute to Pawnee’s favorite miniature horse?

Chris Pratt and an acoustic guitar led the entire cast in a rousing live performance of “Bye, Bye Little Sebastian” Tuesday on Seth Meyers‘ late-night talk show. The hysterically-funny-though-low-rated sitcom took its final bow on the same broadcast channel hours before the “Late Night” tribute aired.

Everyone was there and singing with cigarette lighters up in the air — though two cast members, Aubrey Plaza and the much older Jim O’Heir, were busy grossly making out most of the time. O’Heir even appears to undo Plaza’s blouse — such is her offbeat humor.

Their castmates loved it, as did the Studio 8G audience, which was treated to some “Parks” finale spoilers whether they liked it or not during the afternoon taping.

Watch the video and try your hardest not to sing along with the chorus — we dare you.
