"Amusement Parks U.S.A." was released as the B-side to "Salt Lake City" on a promotional single.[1] It was also released as a single in Japan, backed with "The Rocking Surfer."[2] The song was omitted from the 1980s re-release of Summer Days (and Summer Nights!!) (retitled California Girls), along with "I'm Bugged at My Ol' Man."
Critical opinion
AllMusic critic Richie Unterberger described the track as a "subpar effort" and as one of the "throwbacks to the empty-headed summer filler of previous days" on Summer Days (and Summer Nights!!).[3] Author Jim Fuselli called the track a throwback "to the group's happy-go-lucky days," after also describing the album that it first appeared on as lacking "a coherent lyrical theme."[4]
