George Square was handed over to BBC Radio 1's Big Weekend last night, when top DJs performed to a crowd of 14,000 music fans.
(Some might question why the Square had to be used for this event. Glasgow Green is being used for the main event tonight, when a crowd of 50,000 is expected).
The main stage was at the west side of the Square but for around 5 minutes of last night's several hour show, the crowd was asked to turn and face the City Chambers as something amazing was about to happen ... they were then treated to this:BBC Radio 1 Video: Lighting up George Square
The City Chambers as you have probably never seen them before and the most amazing part is that Gordon Mathieson's face is nowhere to be seen.
(It might be tempting to give up at the start of the video, but I think it is worth persevering).
