Subsonic Radio

Hello all. I am new to here and am trying to find a very rare (atleast to me) and specific background track. Its the Tom Dooley (area music) that i believe is played in the Splash Mountain area in Disney World. There is no voice to the track, mostly harmonica. Any idea where I can this for download? I've checked youtube, almost every site I can think of to find it. Any suggestions would be much appreciated.
