As the film ends with the Blues Brothers and band playing "Jailhouse Rock", there are several cuts starting with the second verse that feature the castmembers who are professional singers singing lines of the song with their names on the screen.
Many of the film's crew members are shown singing "Jailhouse Rock" (as the credit "Crew" appears on-screen) during the final number.
The Universal logo is missing from the beginning of the film, and in fact is not used at all. The film begins with the title card "A Universal Picture." The logo is added on the DVD release.
During the cast roll call during the closing "Jailhouse Rock" number, 'John Belushi' is credited as Joliet Jake and Dan Aykroyd is simply credited as Elwood.
