Fiona McKinlay's verdict: three stars

It would be hard to deny that Olly Murs puts in the effort. His enthusiasm and eagerness to please is at 110 per cent for the whole show. Every movement is exaggerated as if he is trying to pack the energy of a five piece boyband into just one man.

Scrape beneath the cheesy - and sometimes sleazy - surface and Murs is a decent singer with a decent repertoire of songs. Some of them certainly aren't outstanding, but they rarely grate. Newer songs too show the kind of creative progression that so many of these talent show graduates fail to accomplish. Encore tune Nothing Without You is one such gem.

He's the kind of intense entertainer you worry might single you out for not putting your hands in the air - or, as he does, give a fan back her bra and tell her to put it back on. His attempts at speaking Scottish are cringeworthy at best, but the show isn't all that bad. He hits the notes, the band play well, and occasionally, Murs shines.

Those glimmering moments, mostly in the latter half as his voice seems to warm up, show promise that one day he might take the reigns from Robbie Williams. Four albums and three nights at the Hydro, though, perhaps says being Olly will do just fine.

Stand out songs like Up, which he performs with support act Ella Eyre, Dear Darlin', which appears in stripped back form, and Troublemaker, will be worthy of mainstream radio rotation for years to come. Even when he peaks, though, Olly never quite raises the roof. A medley appearance of Mark Ronson's Uptown Funk creates the most movement in the room - a sign of where Olly needs to be heading next.
