The final song in this mini series hasn't just popped into my head, its been kipping in the attic ever since my son was born. Sweet Baby James is 50% cowboy song, 50% lullaby, 100% immaculate. There may well have been better songs written than this; but not many. Even its writer, James Taylor, said it's the song he's most proud of. I can't disagree with that.
