text: how can i find this pbs documentary? my brother and i once saw a fascinating documentary on television about the industry where people send in song lyrics and musicians write and record the songs for them, then send them the recording.  this documentary included discussion about what kinds of people send in these lyrics, the musicians who write the songs, and so forth.  it was the most fascinating documentary on something i didn't care about i've ever seen.  i'd like to watch it again, but i don't know what it's called.  does anyone have an idea how i can get a hold of this program? the title is "off the charts: the song-poem story"  it's available on amazon.com for $17.99
