In the end credits, some of the songs have the wrong songwriters listed underneath the titles, i.e. the music of "Following the Leader" is accredited to Arthur Quenzer with Paul J. Smith (under the name of Paul Smith) as the lyricist, and also Phil Baron (who here is listed under the moniker of "Phillip Baron") is credited as the writer of "The Great Outdoors" instead of George Wilkins.
