Yer Blues by The Beatles on The White Album
Quick story...
When my wife and I were 19 y/o kids in Ohio, I said "Let's go to LA". We headed west and found an apt in Hollywood.
One Sat afternoon, the old clock radio sitting on top of the 'frig was tuned to KHJ and heard a new DJ playing these songs I had never heard. He would say a few words about what was happening in the recording studio or what the song was about.
The DJ? George Harrison
The album? The White Album
A week later I bought it at a shop on Sunset.
