What beatles' songs were played with maracas?

Normally, Ringo would play that instrument if the song they were recording called for them. But either of the other three would have been more than capable of playing them.

Although maracas are indeed percussion instruments, they would only have been played by Ringo if there was no other percussion in the song (maracas don't normally replace drumsticks). I believe that John was usually the maraca player since he was (technically) the rhythm guitar player. All of this is a moot point, though since the songs which they recorded with maracas were never performed live.
