stevie/robert plant similarities?

this may be farfetched but....my other favorite band besides FM is Led Zeppelin....i can't help but notice some similarities between Stevie's singing (of her past years) and Robert Plant's.

Robert's voice through the 70's went downhill in terms of his live performances. I have a lot of boots of their shows and he slowly lost a lot of range through the years and couldn't hit the high notes. I'll hear him singing at certain parts and i can't help but think that it's Stevie during the RAL era.

But, the thing that strikes me is that Stevie, during the RAL tour, really reminded me of him especially in the way that she use to go nuts, being spontaneous and screaming out the words.

JMO though!

PS...they kind of had the same hair for a while there too!
