Zep has been my favorite band since I was 10 (now 63) and have the tattoos to prove it. I was devastated when Bonham passed. I met Plant the morning after a show in Norfolk Virginia at breakfast in the hotel. He was with the entire band (Sensational Space Shifters). We sat and talked with him for the better part of an hour. All I can say is what a dude. We didn't come across as star stuck fans. Said good morning and off he went. Asking us questions, did we see the show, what we thought, where we were from,telling jokes.He was funny, engaging, just a good person. I can honestly say I met my lifelong idol and am all the better for it.
The song you reference is a good example of his unique expression of his talent. But I am guilty of being an extreme fanboy, He and the band did nothing to ever disappoint me. I was always intrigued how they progressed as a band and even more amazed at how he has taken is talents to the level he has on his own,
