Irish singer-actor Wilkinson may be beloved stage actor in the UK, but he may have never had his claim to fame if it wasn't for Eurovision. He represented Ireland in 1978, before his career really took off, finishing in fifth place at Eurovision. Just a few years later, the actor became a theatre star on both sides of the pond for playing Valjean in both the West End and Broadway productions of "Les Miserables". He continued a steady career on the stage in the UK, and in 2012, appeared in the "Les Mis" film in a cameo role alongside the movie's Valjean, Hugh Jackman.
