I grew up listening to Offspring, once saw them at Wembley stadium a while back and it was brilliant, except my friend got warned for crowed surfing, did it twice more then had to sit up in the stands next to the stage for half an hour with a security guard haha.

No crowed surfing at Wembley! There was also no smoking (before the smoking ban). You just needed to stand up the stairwell a bit to see hundreds of orange glows and trails of smoke floating up lol
