A must for music fans, this brand new documentary about Bowie is a welcome addition to the Saturday night schedule. Five Years explores, well, five key years in Bowie's career: We catch up with Ziggy Stardust in 1971, rediscover the Then White Duke in 1975, remember the 1977 success of Heroes, and dabble with Scary Monsters in 1980. And just when you think you've had enough, we zoom right the way up to 1983, when Let's Dance became a global success. Where's Commander Hadfield when we need him eh?
