Tattie, the 'Make a link' thingy seems to restrict URLs to 128 characters so your link to
http://www.ed.ac.uk/schools-departments/literatures-languages-cultures/celtic-scottish-studies/news-events/greig-duncan-songs/greig-duncan-songs
was cut to
http://www.ed.ac.uk/schools-departments/literatures-languages-cultures/celtic-scottish-studies/news-events/greig-duncan-songs/gr
and therefore doesn't work :-(
