One of the greatest songs about the hope of hopes; freedom for all.
Donny was in that category with Marvin; he was, as we used to say, deep. Before I heard Extension of a Man he'd had success with Roberta Flack on some pop hits (Where is the Love the most well-known) and I just thought he was good, not great. The one exception that made me take note from the album with Roberta Flack was, For All We Know.
When I heard this cut I was a young man, and spinning out of control. It's safe to say that music let alone one song didn't turn me around, but it did mean a lot to me.
Today I listen to this and think about that time, the early 70's... a lot was happening besides me being crazy... Donny sounds even more relevant, powerful now, and, like Jimi and Marvin, deep.
