It was the saddest Nationals yet.

The New Directions took the stage in Tuesday’s episode of “Glee,” where they surprised both the show’s audience and Finn Hudson’s (Cory Monteith) mom and stepfather with a set list comprised of Hudson’s favorite songs.

The glee club dedicated their entire performance to Hudson, and closed with U2’s “I Still Haven’t Found What I’m Looking For.”

“This was Finn’s favorite song,” a teary-eyed Carole Hudson-Hummel (Romy Rosemont) told Burt Hummel (Mike O’Malley). “They’re singing all of his favorite songs.”

As the New Directions sang their hearts out in the moving performance, TV audiences watched flashbacks of Hudson’s most memorable moments on Fox’s musical series, from him singing in the shower to a tender moment between him and Mr. Schuester (Matthew Morrison).

At the end of the song, Sam Evans (Chord Overstreet) proudly held up Hudson’s drumsticks.

Monteith died in July of last year at 31. “Glee” creator Ryan Murphy previously paid tribute to him with an entire episode dedicated to the death of his character.
