ITV hasn't nailed the formula for a late-night chat show (although Dermot O'Leary is giving The Nightly Show a pretty good crack), but it's hard to fault its ability to put on a mainstream variety show - if you like that sort of thing. The scheduling feels odd (surely this is one for the weekend?), but the line-up ticks a few boxes. Joining the host, Bradley Walsh, are the Brit award-winning singer Emeli Sande; the magician Pete Firman; the returning pop ensemble Steps, performing their comeback single Scared of the Dark, Ben Forster singing The Music of the Night from The Phantom of the Opera; and talent from the Chinese State Circus, who will leave mouths agape.
