'He'll either win the Victoria Cross or go to prison.' So said Keith Allen's headmaster, back in 1966. A Navy baby, Allen was moved from place to place, always leaving a trail of destruction in his wake. He could have been a footballer if his criminal career hadn't got in the way. Keith's chequered past has seen him keep a pet lion, down a mug of his own urine on stage with his mother looking on proudly in the audience and write a number one pop record. He has been incarcerated for smashing up a night club and almost sued for claiming he slept with a Dame. Since then, he's become renowned for his extrovert and contentious behaviour, his radical opinions and his acting pedigree. But at 54 years old ...has he finally grown up? Revelatory and unapologetically honest, "Grow Up" takes you on a break-neck journey through the chaotic life of someone who's broken all of the rules.
