In the case of the Lord of the Dance I think it's be a good idea to have a link to http://www.stainer.co.uk/lotd.html, <the link Barry had there) actually in the DT.
It'd mean that people would be able to get the song through the DT, which is good for the DT, and also it would be an act of good will to Sydney Carter. I'm sure it wasn't his idea to pull the other songs out of the DT as well as "Lord of The Dance", where, thanks to Flattley, there were special reasons. He really is an lovely man.
