Betty Blue Eyes beautifully evokes that Bennett North, preoccupied with good dinners and bad feet. It contains Reece Shearsmith singing the best song ever written about verrucas, a duet performed with clothespegs on the nose, a Lindy-hop in an air raid, Sarah Lancashire tearing off her pinny for a Ginger Rogers routine, and a chorus of town councillors in a pub urinal. There's an animatronic pig, and a dream sequence involving Prince Philip doing a soft-shoe shuffle with his hands behind his back. You can't stop laughing.’
