By autumn 1963, Jagger had left the London School of Economics in favour of his promising musical career with the Rolling Stones. The group continued to play songs by American rhythm and blues artists such as Chuck Berry and Bo Diddley, but with the strong encouragement of manager Andrew Loog Oldham, Jagger and Richards soon began to write their own songs. This core songwriting partnership took some time to develop; one of their early compositions, "As Tears Go By", was a song written for Marianne Faithfull, a young singer Loog Oldham was promoting at the time. For the Rolling Stones, the duo would write "The Last Time", the group's third No. 1 single in the UK (their first two UK No. 1 hits had been remakes of songs that had previously been recorded by other artists "It's All Over Now" by Bobby Womack and "Little Red Rooster" by Willie Dixon) based on "This May Be the Last Time", a traditional Negro spiritual song recorded by the Staple Singers in 1955. Jagger and Richards also wrote their first international hit, "(I Can't Get No) Satisfaction". It also established the Rolling Stones' image as defiant troublemakers in contrast to the Beatles' "lovable moptop" image.
