British rockers the Klaxons are in shock after discovering 500 copies of their new single It'S NOT OVER YET have been pressed with a B-side performed by an unknown band.
Fans who bought the limited edition seven-inch single were treated to an unknown song by a mysterious band when they flipped the record over.
And the band members are similarly confused, because the B-side should have featured an etching and no music at all.
Frontman Simon Taylor says, "I think the people at the pressing plant have their eyes on different pies.
"I used to get really into those fan websites, where people would claim that there was some kind of link between the hidden tracks and the other ones. I like the idea that there is some sort of magic behind it. Maybe there is."
