Query: A treasure

I've been an insane Elton John fan since I was 12. This documentary shows moments from an old ABC special that was broadcast around the late 70s. It shows my favorite scene where Elton is playing the song "Harmony" a pump organ outside while the band is sitting around a tree. That scene alone was worth the cost. The types of things Elton and Bernie discuss are the things I used to always want to know about. The "process" I guess of crafting a song. I learned a lot of things I never knew before. Goodbye Yellowbrick Road is arguably Elton's greatest album. I've always thought Captain Fantastic and the Brown Dirt Cowboy rivaled it.
