BG: song title?

[Julie Yoder]

My husband and I attended the Gettysburg Bluegrass festival in May.  Ralph Stanley sang a song, which had something to do with horses.  My husband has become a very big fan of Ralph, and I would like to get him a CD that contains that song.  Does anyone know what the song is called, and what CD I might find it on?  It seems to me it had something to do with "2 horses".   Thanks!
