I agree about Fallin' Ditch. it definitely stands out in terms of the bass playing; that's how I was able to get it to stick in my mind.
What are your thoughts on Big Joan? It's funny, in an interview with Drumbo he said that that's the one song he doesn't miss playing, or something like that. It's obviously a very obnoxious song and probably somewhat overlong. the lyrics are hilarious though, and I find that crazy riff running through my head more often than not.
