Plant made the nighttime talk-show cicuit after the Kennedy Center honors in 2012. I'm pretty sure he spoke about leaving the LZ music in the past, as he no longer interested in performing it. He was still interested in new musical horizons, blah, blah, blah.
I have to wonder if he wasn't stung a bit by Ann Wilson's vocals during the tribute performance of Stairway.
Yeah, I saw the video of the Kennedy Center Honors for LZ. Ann and Nancy Wilson ought to be ashamed of themselves for the schlock rendition of Stairway to Heaven that they foisted upon that audience. There was one shot of Plant, and he seemed to have an expression that said, "Oh, dear God. Couldn't they have found someone else?"
Don't get me wrong. Heart's music was pretty good at first. Then after Little Queen, they followed the same schlocky, milquetoast formula that caused Styx to fall off he map.
Yeah, the Wilson sisters really trashed that song.
