The song "I, Me, Mine" by the Beatles is known as the last song recorded by the Beatles. I was reading that Phil Spector took the recordings and looped the second verse to make a final third verse. I was surprised to read this and took the song's verses and played them side by side (Verse 1) favoring the right speakers and (Verse 2) favoring the left.
To my disbelief there was playing the exact same piece of recorded music. I gather because it such a fine piece of work, that when you do loop it you don't even notice because it's so fluid. I had tried this with my own tracks (in creating a backing track and on a full chorus) that I wanted longer.
I actually like the orchestrations even though Paul McCartney and the Beatles may have not liked what Phil Spector added. I wrote a song called "The Climb" which was also a "Heavy Waltz" in 6/8.
