The "original" Lyke Wake Dirge tune was lost, so far as can be told, though it has been sort of described. Blowzabella published a rather odd one, but didn't say where they got it, so that has to be discounted for the time being. The tune generally used today was written by Harold Boulton only a little more than a hundred years ago. See previous threads, which have links to all the words and music (except for the mysterious Blowzabella tune) so far as I recall.
