What songs did Keith Richards write?

Answer 1

I suppose you mean within the Stones. Most tracks truly are a combination of Jagger/Richards, though there are some that either Mick or Keith have written mostly or completely on their own. Probably the most well known "Keith song" is Happy, from Exile on Main St. Some other examples are Connection (Between the Buttons), Ruby Tuesday (Also on Between the Buttons), You Got the Silver (Let It Bleed), Coming Down Again (Goats Head Soup), Before They Make Me Run (Some Girls), All About You (Emotional Rescue), Little T&A (Tattoo You), and so on and so forth. Gimme Shelter is said to be a predominantly Keith song, written while waiting for his then-girlfriend, Anita Pallenberg, to finish filming the movie Performance with Mick. There are plenty of other songs that Keith did a lot of work on on his own that Mick tweaked in-studio.

Hope this helps. :)
