I received a message informing me that the Hash House Harrier Dirty Songbook link is no longer operable. This was indeed a sad state of affairs, but I think it's not so bad as it might seem. If you go to harrier.net, I think you'll find that the Hash House Harrier Songbook will suitably satisfy your prurient interests, even though the word "Dirty" is no longer in the title.
