said, "The amazing thing is that although Mick and I thought these songs were really puerile and kindergarten-time, every one that got put out made a decent showing in the charts. That gave us extraordinary confidence to carry on, because at the beginning songwriting was something we were going to do in order to say to Andrew [Loog Oldham], 'Well, at least we gave it a try ... Jagger opined, "We were very pop-orientated. We didn't sit around listening to Muddy Waters; we listened to everything. In some ways it's easy to write to order ... Keith and I got into the groove of writing those kind of tunes; they were done in ten minutes. I think we thought it was a bit of a laugh, and it turned out to be something of an apprenticeship for us." 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.

In the studio, the band have tended to use a fluid personnel for recordings and not use the same players for each song. Guest pianists were commonplace on recordings; several songs on Beggars Banquet are driven by Nicky Hopkins' piano playing. On Exile on Main St., Richards plays
