Ringo (1978)

In this update of the "Prince and the Pauper", Sir Ringo Starr is the most famous rock drummer in the world, but has become bored with his life as an iconic pop star, while Ognir Rrats is a shy, bullied nobody with a lousy job and an abusive father. When Ringo sees Ognir and notices they share a strong resemblance to each other, they decide to switch places. Once Ringo gets a taste of Ognir's troubled life, and Ognir is caught up in Ringo's busy schedule, can things be straightened out before Ringo's big concert, later that night?
