Song Sightings:
The Man Behind the Plough
Shalo Brown

You could delete messages when all of the songs listed in them have been harvested, or delete the links to the harvested songs. If you do the latter, you could leave up the links to songs that weren't harvested (for whatever reason) and this would be a sort of index for songs that are only in the threads. (I'm thinking about songs in the database that have been zapped by Harry Fox and the like.)
