It was a cover of a Bob Dylan song thatWalk Off the Earthdid five years ago.
They performed it once, just for kicks.
We got an email in about July.

It was pretty cool.
And its just an acoustic cover, not a lot of bells and whistles.
It was one of those tearjerker songs.
We were kind of just hanging out and had shot another video that day, adds Blackwood.
Marshall was like, hey Sarah check out this song.
We should cover it.
We sat down and started doing some harmonies and we were like, lets film this and record it.
Good thing they did.
It really sang to us because of Jamie and Claire being separated.
Thats why it won out.
We very rarely use contemporary songs.
But that one really worked out.
This isnt the first time the bands music has been used on TV.
Have a listen:
Outlanderairs Sundays at 8 p.m. on Starz.
