Mine is that I don't even care for Plant very much, and I wish their singer had been Ian Gillan.
This opinion will probably get me roasted pretty hard, but I've gotta be honest!
My absolute fav ever is "Friends"
the others are:
Achilles
Ten Years Gone
No Quarter
In The Light
Battle of Evermore
Fool
The Rover
Black Country Woman
Carouselambra
No worse than most of the clown costumes Plant has sported over the years...remember the Now and Zen cover? The Honeydrippers? All the ethnic looks he's tried to pull off?
