The “Smash” co-stars reunited to sing a song honouring those on the frontlines in the war against COVID-19. McPhee and Jordan have both appeared in the Broadway musical Waitress, albeit at separate times.

They decided to right that and sing a duet of “You Matter to Me” from the Broadway musical. The song was performed in honour of frontline workers.

“If you are someone who has not missed a day of work, putting yourself or your family at risk, we dedicate this to you,” McPhee wrote when sharing the duet on Twitter. “You matter.”
