Despite the not-quite stellar weather last night, 70,000 fans arrived at Slane Castle to see the Foo Fighters, Hozier and other acts - and by all accounts, it was one of the better gigs there in the past few years.

After the Foo Fighters had left the stage and fans were making their way towards the exit, some decided to have a little fun with the Garda safety announcements playing over the speakers.

If Hozier deserves a sing-along, then why not the Gardaí too?
