Olly Murs was replaced by an up-and-coming Scottish singer discovered in a hotel bar after he had to cancel his performance at the last minute - and Gary Barlow thanked him for 'saving the day'. Fans were full of praise for the young talent who stepped in for Olly when he couldn't make it to open for Take That at their Glasgow gig in OVO Hydro. Olly was all set to warm up the crowd for the legendary 90s group over a three-night stint but was left stranded due to a series of flight delays.
