Fall Out Boy Released An Unheard Demo Via A Fan Scavenger Hunt

Before Fall Out Boy headlined the O2 Arena on Saturday, Pete Wentz spent his pre-show time in London hiding exclusive T-shirts and USB sticks for fans to find.

The sneaky bassist snuck the packages under a traffic cone in the city, and also in two spots around the venue, before waiting patiently for fans to grab the goods.

Edith Gervin was one of the lucky ones, and has uploaded the contents of the USB stick – an unheard demo of Young And Menace – to YouTube.

See how it all unfolded below, and keep scrolling to hear this rare demo.

Oh, and while you're here, pick up this week's issue of Kerrang! for an exclusive commemorative UK tour print!

Talk about bands going above and beyond for their fans, eh?

Fall Out Boy headline Reading & Leeds in August – don't miss 'em.
