sources have varied in crediting the piano on the track. the original "beatles for sale" liner notes, by derek taylor, said that "george martin joins john and paul on one piano", implying an overdub by all three that was added after the basic take. in the 1988 book "the complete beatles recording sessions", mark lewisohn described the recording as a single take with no overdubs, with "all the beatles on their familiar instruments" and martin on piano.
