Green Day frontman Billie Joe Armstrong issued an apology to Glasgow fans after their Bellahouston concert was cancelled just hours before it was due to start.

The singer recorded a message for fans as crowds began to gather outside the Blythswood hotel where the band were staying. 

He said: "Hello Glasgow kids, Scotland. Yeah this is a bummer and we really wanted to play and I guess it was just unsafe for everybody in the crowd, the crew and the band."

"Right now I can actually hear people gathering out front of our hotel singing. I heard you sing Still Breathing, which is beautiful. Alright."

"What a bummer."
