Indeed, the disguise worked so well that the bassist wondered if the same stunt could be employed by the whole band. Just as it did with Paul, assuming different identities could free the band to try different things by allowing the group to get outside of themselves. Quoting Paul: "With our alter egos we could do a bit of B. B. King, a bit of Stockhausen, a bit of Albert Ayler, a bit of Ravi Shankar, a bit of Pet Sounds, a bit of the Doors; it didn't matter, there was no pigeon-holing like there had been before" (Miles, page 306). After a crazy year in 1966 - in which they stopped touring due in large part to the delirium of live performances - the band found the notion quite appealing, and decided that for their next album they would not be the Beatles.
