Katherine, if you enter a key word into the box upper right, you will find the songs in the database. The word "asshole" will get you a number of hits, including the Dogs Meeting, the tune, and the information that it is performed by John (Roberts) and Tony (Barrand).
I thought I had perhaps heard Stan Hugill's name associated with it, but I'm sure other Mudcatters will know more.
Thank you for being considerate of my finer sensibilities, they're around here somewhere, I know it, I expect them to show up any day now...
Blessings,
Barbara
