'Glee' goes 'Grease' with 'Summer Nights' cover

Now that Sam has returned to McKinley High and "Glee" is addressing his summer romance with Mercedes, it seems pretty fitting that the former couple would cover the most famous showtune about seasonal loves -- "Grease's" "Summer Nights."

The "Glee" version, which just leaked online, is pretty faithful to the original, with the respective New Directions members spilling all to their groups of friends. Speaking of, the seldom-heard Rory and Sugar both get cute solos as inquisitive pals.

Also, Sam sounds very Travolta-like during certain points of the song, yes/no?

New Directions will also cover Rihanna, Maroon 5 and the Rolling Stones during "Yes/No."

Check out the tune before it's pulled from YouTube and let us know how excited you are for "Glee" to go "Grease" on Tuesday, Jan. 17.
