Maybe that's why it sounds familiar; 1966 was an interesting year.
It reminds me of the time when Jimmy Page was in the Yardbirds. I recall watching a television program and noticing that he had a new singer in the band, but I don't remember the name of the program. I remember where I was, what I was doing, and all of that. I'm wondering if it was near the time of the the February, 1968 show at the Whisky.
