Just finished reading "Walk This Way" again. I had to go back to catch all the Zeppelin references I missed the first time I read it. Glad I did, they were mentioned SO much in it.
No Quarter definitely. This is probably horrible to say, but I never fully appreciated the song until I heard the live versions. I love the live versions of BOE too.
RAH. I love TSRTS, but they seem a bit tired. Just to add to what Queen said - TSRTS seemed a little more about the "rock stance/rock star", and RAH seemed more about the music with more innocence. But both are great for sure.
