GM has confirmed that its new Cadillac campaign will officially be introduced during Super Bowl XXXVI to the hard-driving Led Zeppelin tune, 'Rock and Roll', according to a report in Adweek. The song was originally released in 1971 on the group's 'fourth' album. The Adweek report quotes Mark LaNeve, Cadillac's US General Manager, as saying that this will 'demonstrate that Cadillac is unafraid to lead in styling, performance and functionality'.
