John loved many different classical composers but Pachelbel was one of his most favorite. In particular he loved the Canon in D Major.
This track is from the lost Earth Rider album. I don’t believe that it was ever released though there are a number of pretty bad bootlegs floating around in the world. This is one of the cleanest
that I’ve heard. The vocal is Buffy; clean and pure. The lyrics are by John and the music is Pachelbel.
