(CNN) — It's almost time for the "Orange is the New Black" cast to say goodbye. And we can already tell it's going to be a tearjerker.

Ahead of the debut of the Netflix series' final season, cast members sang lines to the show's theme song in a bittersweet promo video.

Some of the stars included Uzo Aduba, Dascha Polanco, Danielle Brooks, Taylor Schilling, Natasha Lyonne, Kate Mulgrew, Adrienne Moore, Jackie Cruz and Diane Guerrero.

In an a capella rendition of Regina Spektor's song "You've Got Time," the actors take turns singing the lyrics as they walk around the show's set. But rather than the upbeat tone of the original, their version is somber and emotional.

The lyrics will pull at your heart:

The animals, the animals

Trapped, trapped, trapped

Till the cage is full

The day is new

Everyone is waiting, waiting on you

You've got time

Think of all the roads

Think of all their crossings

Taking steps is easy

Standing still is hard

Remember all the faces

Remember all their voices

Everything is different

The second time around

And you've got time

Spektor shared the video on Twitter and thanked the "OITNB" team.

"So misty, so beautiful! Thank you for everything to the wonderful women and men of @OITNB- I loved singing along with you," Spektor tweeted.

Netflix confirmed last October the seventh season would be the show's last.

The series' final season is available on Netflix July 26.
