Musically, The Who were the high point of the evening. Their 4-song set ("Who are You," "Baba O'Riley (teenage wasteland)," "Behind Blue Eyes," and "Won't Get Fooled Again,") was the only performance other than McCartney's longer than 2 songs. After "I'm Down," and another recent song or two, McCartney played his new song, "Freedom," and then brought everyone back on stage for "Let It Be," the grand finale. Then, Peter Townsend whispered in McCartney's ear, and they played "Freedom" again.
I like to think of that song as the antidote to "Give Peace a Chance" (Chorus: I will fight for the right to live in freedom!)
