Listen to The Who on iHeartRadio

Who fans are getting their first listen to Pete Townshend's new song, "It Must Be Done."  The track will be featured in this week's episode of FX's "The Americans," and serves as the music bed for the show's promo. 

Townshend wrote the song with Nathan Barr, who creates the music for the drama series.  While Townshend and The Who's music have been used in TV shows before, "It Must Be Done" marks the first time the rocker has provided original music penned specifically for a certain show. 

"The Americans" episode with "It Must Be Done" will debut on FX this Wednesday.
