NOW ALL THE WOODS ARE WAKING is a round. There are no more lyrics beyond what you posted.

It is on the children's album "My Best Friend : Songs to Grow On" by Lisa Monet. You can hear it on Spotify.

Also, it's in at least one songbook: Round the World : Teaching Harmony with Multicultural Rounds and Canons by Cheryl Lavender (Milwaukee, WI : Hal Leonard Corporation, 2012)

You can see the music notation in this video: http://www.youtube.com/watch?v=2ijQgz1kIE8.

There is an MP3 file on this page, of some adults singing the round.
