Here it is, 4 days after my comment was posted about the flip side of Fess Parker's "Ballad of Davy Crockett" and I just now recalled what the flip side of my copy of the single was, and I have to give credit to @paul and his 9 O'Clock #HashtagGames last night, on #MountainSongsOrPoems theme.

Fess Parker sang of a mountain man on the flip side of that Crockett song, and his name was #JohnColter . "The Ballad of John Colter" was on the flip side, and not only that, but TIL Fess Parker wrote it as well as performed it.

"Sing of the bravest mountain man
Sing of the strong and the fleet
Colter's courage was in his heart
And his speed was in his feet".

Wiki was saying that Colter was the first mountain man known as such.
