There was a rumor in the Soviet Union that The Beatles had secretly visited the U.S.S.R. and given a private concert for the children of top Communist party members. They believed the song "Back In The U.S.S.R." was written because of the concert. Actually, some fans still believe so.
Kacey Musgraves originally offered "Follow Your Arrow" to her friend Katy Perry. However, Perry thought Musgraves should record the song herself as it seemed, "like something that you would totally say."
