The Vaccines find the Red Hot Chili Peppers dedication inspiring.

The 'Teenage Icon' band supported the US stadium rockers when they played the UK in June, and singer Justin Young admired how much energy they put into each show.

He exclusively told BANG Showbiz: ''They weren't a band I'd ever really listened to, but one thing I was impressed by was that after thirty years, still, they went out there and gave it everything they had, it didn't feel like a band going through the motions. They were trying to entertain every single person in that stadium, and that was really inspiring.''

The Vaccines only did their first tour in 2010, on which they collected postcards from each of the towns and cities they visited, but with their rapid rise to fame since, Justin - who is joined in the group by Arni Hjörvar, Freddie Cowan and Pete Robertson - says it's sadly becoming harder for them to do.

He added: ''We do still collect, although it was something we started and we were really good at, but then after we stopped having time to do it ourselves. We put them on our rider, but not everybody would get them. There's definitely some holes in the collection. The weird thing is just places you wouldn't even be able to imagine a postcard from, like Sheffield.''
