Jack,
Tim Wallace is also on my list of great undiscovered artists.
I first found him on a compedium of many artists by a folk organization from your neck of the woods (I'm at work so I can't make a specific referral). I finally tracked him down and bought his cassette tape from him through the mail.
I am dedicated to performing his "You Don't Even Care" where ever I can. I want to learn some others including that food/sex song you mention and "The World's Longest Song." Don't let Joe know I mentioned these songs. He'll want me to post the lyrics. He has the lyrics to You Don't Even Care 'cause I sang it in the song circle after Rick's concert in DC last October. They were posted by me on a thread later. The rest of the lyrics are still on the tape.
