The format of Elvis' fantastic interview/performance show changes this week as Elvis interviews The Police both as a group and individually (perhaps wise as Andy, Sting and Stewart have always been a bit combustible in tandem). Elvis and The Police have toured together recently and it shows in their music. Sting performs the original version of the Police's big hit Roxanne and then Elvis duets separately with both Sting and Andy. For the grand finale Elvis and The Imposters join forces with The Police for what the Sundance web site promises is "an unprecedented 'mash-up' of a Costello classic and a Police essential, as well as a surprising cover of a time-tested hard rock anthem".
