Sharyn,

On my most recent CD, Low Rent District, I included a live performance of Woody Guthrie's distinctive version of Lonesome Valley in which I sang a couple of verses of Guthrie's You Got to Go Down and Join the Union,both being to the same tune. Ludlow Music is the copyright holder for both songs, so I called them to ask what I should do. Not surprisingly, they said I should pay the licensing fee for both songs as if I had recorded them separately. That's what I did, but instead of paying Ludlow directly, I went through the Harry Fox Agency website, which is what they strongly recommended I do. The fee for each of the two songs was 9.1 cents per CD plus a $10 service charge. The Harry Fox Agency e-mailed me an acknowledgement immediately and the actual mechanical licenses within 24 hours. It was all very painless.

Best of luck.
