Sorry if I seemed a bit stern, Dave; bad day, and nothing personal meant, as I said.  Sleeve notes are important, though, if they give information about the song, so it really is best to include any background information you may have.  I've spent an awful lot of time identifying sources and tunes for song texts that people have posted here in the past with no real information given, so I do tend to get a bit impatient about it.  A song isn't music without a tune, after all, and with traditional songs the background can be very important indeed; here, for example, Snuffy's information from the sleeve notes meant that I could find the tune, and the missing half of the song.
