The Chewin' The Fat star surprised hundreds of travellers when she and 33 singers of Voice of the Town showed up to sing 'I belong to Glasgow'.
The unexpected performance was recorded to be part of the upcoming four-episode documentary 'I Belong to Glasgow' for BBC Scotland, presented by Karen Dunbar, Sanjeev Kholi, Elaine C Smith and Alex Norton.
Madaleine Pritchard, musical director of Voice of the Town Glasgow, said: "It was amazing how people forgot their routines to join us and have some fun."
"I loved when these guys came out singing, they just made my day", a traveller said.
The 'I belong to Glasgow' documentary will be broadcast in spring, and will show the city as it stands in 2014, not dwelling on the historical images.
Still Game star Sanjeev Kholi went back to school for the documentary. You can read about it here.
