I wouldn't call changing a song to fit your own sensibilities "arranging," I'd call it "adapting." I think the first thread I ever started here was to post my adapted version of Bob Gibson's "Abilene." I changed one line in the second verse and added a couple of verses because the original seems to me to be kind of a secular spiritual, and I wanted to emphasize that. There are in the DigiTrad additional verses to the song which I don't feel add anything to it but length. I sang the song last night in the Starry Plough--song and singer well received.
