Phil Collins joined as the new drummer in August, also becoming an important backing vocalist, but they were unable to find a suitable replacement for Phillips. This led to the group completing the first half of their 1970–1971 tour as a four-piece with Rutherford playing rhythm guitar and bass pedals and Banks playing lead guitar lines on a Pianet through a distorted fuzz box amplifier in addition to his own keyboard parts. Banks credited this to improving his technique as it required him to play two keyboards simultaneously. The group felt that Collins was the best drummer they had worked with at that point, and his playing style and musical tastes gave a new dimension to their sound. Some songs were not practical to play live as a four-piece, so they decided to look again for a lead guitarist. In November 1970, Mick Barnard joined the group on recommendation from Friars Aylesbury's David Stopps, and "The Musical Box" was added to the live set. However, the rest of the group quickly realised that Barnard was not up to the same standard as the others, and they kept a look out for a better player.
