The rock n roller stopped by the Tonight Show last night to promote his new venture.

The legendary Rolling Stones guitarist chatted it up with Jimmy Fallon about his new book! Keith has penned a new children's book, yes, children's book. It's titled 'Gus & Me:The Story of My Granddad and My First Guitar.'

The book tells the story of Richards’ relationship with his grandfather, Theodore Augustus Dupree, a musician who had seven daughters, and one male grandchild with whom he developed a special bond. The book was illustrated by his eldest daughter, Theodora Richards.

The book is perfectly timed as Keith has recently become a grandfather for the fifth time!
