Longer Version of Monroe's "Crossing The Cumberlands?"

I'm in the process of organizing a mess of a digital library of music and I found a one-off file which is a recording of Bill Monroe's "Crossing The Cumberlands." My quick research shows the recordings of this song to be less than three minutes, but the version I have is three minutes exactly. It doesn't sound slowed down to me when compared to the two minute recordings, although I admit this is a possibility. It doesn't sound like a live recording either. Does anyone know what album this recording is from?
