The Robert Johnson Songbook is an album by the British blues band the Peter Green Splinter Group, led by Peter Green. Released in 1998, this was their second album. Green was the founder of Fleetwood Mac and a member of that group from 1967–70, before a sporadic solo career during the late 1970s and early 1980s. The album consists of songs composed by legendary blues artist Robert Johnson, and featured a guest appearance by Paul Rodgers, ex-lead vocalist of Free and Bad Company, who later worked with Queen.
