Larry Crane did not write any songs, I checked all my records and cd's. He was credited for playing acoustic guitar, electric guitar, mandolin and back ground vocals. He was very good too. I think Larry may regret leaving John and the band, not really sure how he left it. Maybe John should check it out.
If you dont consider music to be part of the song then he never wrote any. The fact is John only gave Larry credit for two songs. He wrote the intro to "I need a Lover" just to name one of many. Larry had a hand in writing all of the guitar work on those albums, and many other parts. If you are interested in knowing how it all happened I am writing Larry's biography, and it should be available soon. Also, he absolutely does not regret leaving.
