I should know better than to put WWW addresses in angle brackets. The Faery Lore site is http://faeryland.etsu.edu/~earendil/faerie/index.html . It says it will move after "a few more months". It has a clip from Loreena McKennit's recording of "Stolen Child".

The Yeats sites are at http://www.maths.tcd.ie/pub/yeats/Index_html and http://www.geocities.com/Athens/5379/yeats_index.html
