well I am partial to this here website, which, I kid you not, in the about to be published book "Religion for Dummies" is listed as on os the top ten religious websites in the world and THE top website on pagan religions:
but then I am partial ;)
Media Coordinator, The Witches' Voice
p.s. there is a whole section called (I think) "The Music of Witchcraft" which lists many contemporary pagan musical artists (me included).
as for Morris Dancing, I plan to get up at dawn this Monday and watch 'em do their thang with a (skinny little) maypole on the Charles River...lots of pagans are into Morris Dancing but I do not tend to agree it has its roots in anything other than folk ritual traditions, which, along with the ceremonial stuff borrowed from Crowley and Gardner, and the woodcraft/dancing in the woods stuff from England, and who knows how many other bits of amalgam, out together what has become known for better or worse as modern witchcraft/Wicca/Neo-Paganism what have you...
there is no one simple answer to any of it but the website mentioned above has a great deal of material...
