Rolling Stone has a new article on Jeff Lynne in which Lynne describes 15 songs he's written and/or recorded, produced, etc. One of the 15 is "Let It Shine", and he offers the following (which doesn't of course really include any new info):
I had just finished George Harrison's album when Warner Bros. asked me to produce Brian Wilson. I was like, "You can't produce Brian Wilson. He's the best producer in the world." But I said yes and I co-wrote a song with him. We wrote "Let It Shine" at his house in Malibu. He was really struggling in his life. It was horrible and he was being treated badly. But you could see what a nice guy he was despite everything happening in the background. It was all very distressing. I only saw Dr. Landy a couple of times, walking around with his cape and walking stick. I don't really want to talk about that, though. Brian's doing great now and has a lovely wife.The full article:
