Hi Challis,
How can I ever be simple again is by Richard Thompson, I just had a look over at OLGA, the words and chords are there, I don't know where you would find the tune, I got it off a Battlefield Band live video. I can't get past the line "she sang like a child...."
What a great thread, makes me want to find the most mentioned songs, just to see if I can get through them.
