I grew up listening to Cat Stevens, too! My mom used to play Father and Son when I was a kid and say, "This reminds me of us." Her favorite song was Moonshadow, though..
Tea for the Tillerman usually does it for me. Miles From Nowhere, But I Might Die Tonight, and Into White being my favorites.
Anyone I try to share the love of Cat Stevens with goes, "I don't get it. I feel like in order to relate to this I need to have a son." Pish Posh. I'm glad you get it!
I listened to some of his newer religiony stuff. It's ok, but Cat Stevens will always be Cat Stevens in my heart.
