It's Saturday which immediately reminded me of this song, written by Sam Cooke (1963) and covered by Cat Stevens (1974). The song was a top 10 hit for both of them.
I worked with Cat Stevens a couple of years after this concert, when he agreed to participate in my first book, Starart. When I was working with him in Los Angeles, he was Cat Stevens and when I went to work with him in London he was in the process of becoming Yusuf Islam. He was conflicted on continuing his participation in the book - which also includes Joni Mitchell, John Mayall, Klaus Voormann, Ron Wood and Commander Cody - since he was 'no longer' Cat Stevens.
He chose to stay in the book because he had made the commitment, however, he did tell out the opening text (written from an interview I did with him) to his section of the book and most of the comments he had made about his art. I digitized the interview and may post it some tim e in the future. Thinking I should also find the original text that was going to be in the book and publish that at some point.
This is one of his pieces from the book. It is Untitled. Definitely inspired by his exploration of Buddhism.
Enjoy the rest of your weekend!
