"The Red River Valley" is a country-folk earworm that's been played and recorded by thousands of musicians, sold millions of copies, and has a place in several music halls of fame. But what appears below the surface of this folksy love song, has some highly controversial, extremely disputed roots. This episode puts "The Red River Valley" on trial and presents evidence from two opposing sides to try to determine the original roots of a song that could have origins in Northern Texas or Manitoba's Métis community. It's up to the listener to decide.
