Maybe Ray was a little shy but, myself, I wouldn't say the interviews are boring. Plenty of them are available on the excellent Kinks At The BBC box set, released in 2012. Introducing the pride of Muswell Hill on Saturday Club back in 1964, Brian asked Ray if he'd describe the Kinks' music as R&B: "It's expression" says Ray, "it's not R&B. It's pop because it's popular... but we express ourselves."
Yes... the brother was peculiar and threw things about a bit...
Brian on Dave Davies
A year on Brian interviewed Ray again, having clearly warmed to him, and asked about his burgeoning career as a songwriter outside the Kinks.
"Dave Berry's just got quite a big success with one (This Strange Effect). The Honeycombs did one some time back (Something Better Beginning). I was amazed the other day when my publisher told me that Peggy Lee's covered one of my numbers. You know, she's one of my idols. It's one called I Go To Sleep - nobody's done it over here." He then adds, rather sadly, "I'd love to hear it."
