Shelley Posen has written an incredible seder song, which I've been nudging him to propagate. The first verse is about zayde leading the seder. When he passes on, the second verse is about father leading it. The third verse is about leading it oneself... Alas, I haven't gotten him to send me a copy (yet), so I can't remember the exact title. He wrote it for a songwriter's group on the topic of "the empty chair" and sang it at last year's Old Song's Festival.--Charlie Baum
