Maybe not pagan songs as such, but some of Cloudstreet's work might fit the bill. Lady Penelope mentions the Green Man; I assume refering to John Thompson's song. He also wrote "Dance up the Sun" as a celebration of Morris dancing and Nicole's "Gypsy" calls on earth, wind, fire and water. Words are on their website - http://www.cloudstreet.org/ourmusic.html    (sorry, clickifier page doesn't appear to be working).   On the CD sales page, click song titles to get the lyrics.
