This hilarious video shows an 86-year-old gran watching a bagpipe rendition of Insomnia by Faithless surrounded by ravers.
Gran-of-three Marjorie Lawrie, who has two great-grandchildren, was watching her grandson Craig Lawrie, 33, perform with his band Drums N' Roses at the Houston Beer Festival on Saturday, in Renfrewshire.
Craig joked that Marjorie 'looked like she was queuing for the Post Office ' as she stood with her arms crossed while a crowd of 2,000 people waved their arms in the air.
