“This song was cut for the Angel Clare album in the early ‘70s, with Roy Halee as my co-producer. I had just split from Simon & Garfunkel, and I was in San Francisco getting married.

“All I Know is a Jimmy Webb song, and I have always been enamored of what a gifted piano player, chord-meister and songwriter he is. I loved that tune, and I went to town on the production. In my current ears, I overdid it.

“The All I Know I put on this album is two minutes and twenty seconds, a shorter version years later, when Jimmy came into the studio, and the two of us – one piano and one vocal – put down another All I Know.

“What’s interesting to me is that it’s the stripped-down version that allows the singer to show his chops and allows the song to emerge even stronger.”
