Singer Susan Boyle has already been announced as a star of Wednesday's opening ceremony, while veteran mod icon Rod Stewart will perform in a homecoming of sorts.
Boyle has sold 19 million albums since her breakthrough performance on a television talent show in 2009, when she left judges speechless with a rendition of 'I Dreamed a Dream' from the musical Les Miserables.
The singer, who hails from Blackburn, 25 miles (40 kilometers) to the east of Glasgow, has since sung for the pope and Queen Elizabeth II, but was tight-lipped about her performance at Celtic Park, home of European football giants Celtic.
Stewart, who was brought up in London but has a Scottish father, is an avid Celtic supporter and is a regular visitor to the historic 60,000 capacity stadium.
