the battle hymn of an tir, and hanrahan's bar, are the only two that i can recal that are interesting enough for me to recall. oh there was something about three ladies from the isle of weight, that was done by ten man mop or steely eye span, or some such. an tir is of course a kingdom in the society for creative anachronism, and hanrahan's bar is in one off centaur's early filk song books. oh there's also men of reisling. an alternative lyric to men of herlic. (which is a castle in cymre, near the cob terminus shared by the ffestiniog and the welch highland railways) and i'll see your old blind dogs, and raise you a whistle binkies.
there was a filk about spider robinson (an sf author, in case anyone doesn't know) "spider oh spider, oh won't you tell us where, o'callahan's is hidden and will do our drinking there"
