The writing of "The Last Time", the Rolling Stones' first major single, proved a turning point. Richards called it "a bridge into thinking about writing for the Stones. It gave us a level of confidence; a pathway of how to do it." The song was based on a traditional gospel song popularised by the Staple Singers, but the Rolling Stones' number features a distinctive guitar riff, played by Brian Jones. Prior to the emergence of Jagger/Richards as the Stones' songwriters, the band members occasionally were given collective credit under the pseudonym Nanker Phelge. Some songs attributed to Nanker Phelge have been re-attributed to Jagger/Richards.
