I'm always a little put off by the slightly sharp vocals on Fool In The Rain. I don't blame Plant as he likely didn't chose the master take, the producer, I presume Page did. I'm sure Page heard it and either it was the best take and a compromise or he likes it sharp.
I'm not fond of the sped up vocals on The Song Remains The Same on Houses Of The Holy.
Small potatoes in a vast and wonderful musical output.
I don't give a shit what they wear, who they sleep with or if they recycle.
