I think this YT is the audio of the tune by the Band (which YT does not fully credit).
there are some triangle parts missing in this performance (I know I was 2nd Triangle in our local band when we played this). We also added in some of the extra bass/G trombone parts in 2nd theme part.
3rd theme of this is based on "I Think When I Read That Sweet Story Of Old"
