Think for Yourself is a Beatles song written by George Harrison. It was included on the Rubber Soul album. Paul McCartney applied a fuzzbox to his bass, creating a fuzz bass effect. In a departure from all precedent, they also used two bass parts on the track; one fuzz and the other regular. John Lennon played organ on this song instead of the rhythm guitar which he usually played. The song is in the key of G major. This song is in The Beatles: Rock Band Rubber Soul DLC.
