I suppose beauty (or value) is in the ear of the listener.
This song and this performance don’t start my engine at all.
But so what? That just me, and it doesn’t take away what the song means to you.
You are correct that 1971 was a MAJOR year of good popular music. When I think of that year, a few hits come to mind;
1. Theme from Shaft, Issac Hayes. 2. Maggie May, Rod Stewart 3. That’s The Way I’ve Always Heard it Should Be, Carly Simon. 4. Mr. Bojangles, Nitty Gritty Dirt Band, If You Could Read My Mind, Lightfoot..and many, many others.
