“I always have so much fun in Scotland and the crowds are always so amazing. So I can’t wait to be back again at such an iconic venue performing alongside such wonderful artists. Will definitely be one to remember… and I love a deep fried mars bar!” – Jessie J
Presented by Alex Jones, the spectacular concert is to be shown on BBC One, ahead of the opening ceremony of the Commonwealth Games in Glasgow.
Previous acts confirmed for the event in Scotland’s capital city include Culture Club, Kaiser Chiefs, Smokey Robinson, Rizzle Kicks, Paloma Faith, Katherine Jenkins, Il Divo, One Republic, Taio Cruz, Alfie Boe and Pumeza.
The music will also be interspersed with comedy on the night, as Bill Bailey performs his unique brand of musical humour with the BBC Scottish Symphony Orchestra and Fred MacAulay makes a special guest appearance.
