You couldn't have answered the question better. Wonderful answer my friend. Oh I love those 77 shows too. I love Plant's cracked and often broken voice the best. So raw and powerful. I also love the Knebworth shows. Hell, like you said so well, I appreciate and love all of it as well.
Gotta say that 2 songs that leave me cold, Candy Store Rock and Hots on for Nowhere. Bonham kind of saves them for me.
And I nominate you for coolest Dad ever 😎
