Interesting read about an upcoming documentary on the piano player Nicky Hopkins. I think I only ever saw him once when he joined Sky for one of their tours in the mid 80s. Like so many session musicians he often got a raw deal when it came to songwriting credits.
In an interview for the documentary, “Keith Richards almost admitted that Nicky was responsible for a lot of Stones’ songs,” Treen said. Even so, all those pieces were credited to Jagger/Richards. When Dawson pressed Richards about that point for his book, he said the guitarist shrugged and said: “Well, that’s the Stones for you.”
