Sorry I can't help with the specific songs you're looking for but you can find chords for "If Wishes Were Fishes" in the DT. Chords for Eric's more well known songs ("No Man's Land", "And the Band Played..., "Safe in the Harbour" can be found in the OLGA mirrors.
I'm always on the lookout for lyr/chords (especially chords)but Eric's material is hard to find and the two older songbooks are out of print. I'll keep you in mind if I come across anything. I saw him back in July and he was great.
