I’ll tell you what, that Gary Barlow can really sing. Every time the pop star performs a snippet of one of Take That’s greatest hits, this strange hybrid of a show lights up. His singing is still properly powerful – authentic, emotional and intriguingly enigmatic – and it’s a thrill to experience it at such close quarters. If only this one-man show had explored the places that Barlow’s music takes him. Instead, this is effectively a shrunken pop concert turned inside out, with the stage patter stretched to breaking point and the songs stripped right back. Could it be magic? No.
