"The Little Girl I Once Knew", released as a standalone single in November, was the last original Beach Boys song issued before any "Pet Sounds" tracks. In December, Capitol issued the "Party!" track "Barbara Ann" as a single without the group's knowledge or approval. Brian expressed to reporters that the song was not a "produced" record and should not be considered indicative of the group's upcoming music. From January 7 to 29, the rest of the band went away on a concert tour of Japan and Hawaii.
