You may have done a double take if you thought you spotted a world famous rockstar on a Glasgow bus.

Glaswegians out and about on the city's public transport system may think they noticed Dave Grohl of Foo Fighters fame driving the X31.

Close, but not quite. 

To celebrate the group performing at Hampden next week, First has hired a Dave Grohl lookalike to join the ranks and leave travellers stunned.

“Dave” was spotted clocking in at the firm’s Caledonia Depot before taking the wheel of the X31 Hampden Express – the same service that will offer Foo Fighters’ fans an easy way to get to Hampden on Monday, June 17.

He also took in the sights of the city along Buchanan Street and around George Square in his new First Bus driver get-up.

First Bus will run special services frequently from 6pm onwards to collect gig-goers from O’Neill’s bar (40-48 Union Street) and drop passengers on Cathcart Road behind Hampden’s West Stand.

A return service will also be in operation, taking passengers back into the city centre via the same route. 

Graeme Macfarlan, commercial director at First Bus Scotland, said: “Having the Foo Fighters in the city is a huge boost and we know people want to get to and from the gig safely and have a good time.

“It’s not every day you think you see a worldwide superstar driving the X31 but what better way to celebrate than having our very own ‘Dave’ join the ranks?”
