appear on compilations after the royalty renegotiation and Roth's lawsuit were credited to Edward Van Halen, Alex Van Halen, and David Lee Roth, with Michael Anthony's name removed from the credits, as evident in the end song credits of the 2007 film Superbad. Michael Anthony's longstanding bass technician Kevin Dugan has noted that the opening title track instrumental from the album originates from a Roland bass synthesizer passage created as an intro for Anthony's in-concert bass solos, and has claimed that he and Anthony wrote and programmed it together.
