Jones, no longer in a band, advertised for bandmates in "Jazz Weekly", while Stewart found them a practice space; together they decided to form a band playing Chicago blues. Soon after, Jagger, Taylor and Richards left Blues Incorporated to join Jones and Stewart. The first rehearsal included guitarist Geoff Bradford and vocalist Brian Knight, both of whom decided not to join the band. They objected to playing the Chuck Berry and Bo Diddley songs preferred by Jagger and Richards. In June 1962 the addition of the drummer Tony Chapman completed the line-up of Jagger, Richards, Jones, Stewart and Taylor. According to Richards, Jones named the band during a phone call to "Jazz News". When asked by a journalist for the band's name, Jones saw a Muddy Waters LP lying on the floor; one of the tracks was "Rollin' Stone".
