Sorry, Willyhillbilly, but if someone in my family took one of my poems and tossed it out on the internet for someone write lyrics to, I'd have them flayed alive.

First off, it's not your poem to publish, and you published it. Second, an artist has certain legal rights to unpublished work that are lost when it is published. Thirdly, now that the song has be broadcast, Amos, who your sister doesn't know from Adam, shares, with her, the rights to the song based on her poem.

That's not even getting into the issues of meddling with someone else's art work--

You may think that your sister will be pleased, but consider this, she wrote it, with her
own sense of how it should sound and feel. Amos has now imposed his sense of how it
should sound and feel(which alters the very tightly drawn meter beyond recognition)--maybe she'll like Amos's "impovement", but I think that if she wanted it to scan that way,
she would have written it that way.

Last, bottom line is that hundreds of thousands of people visit this site, many of whom are musicians and singers who are looking for new material, and who can, and quite possi bly will learn and start playing this song, without you sister's knowledge or permission.

Bad play, artistically and legally. Amos, you should have known better than to post the recording.
