The words to an adapted version of Row Row Row Your Boat can be found in the Judy And David Songbook at: http://www.io.org:80/~jandd/Songbook/R.html#Row Row Row Your Boat. I haven't found the music, but you could try searching via the Children's Music List at: http://www.cowboy.net/~mharper/Chmusiclist.html.

Good luck! - RS
