It’s been well known that Ghost were recording a cover of ABBA’s “I’m A Marionette” as a B-side for their forthcoming album, Infestissumam. What we didn’t realize is that the cover would feature one hell of a guest: none other than Dave Grohl.

According to a pre-order page of Swedish webshop, Ghost’s cover of “I’m A Marionette” features the Foo Fighters frontman on drums. In fact, Grohl supposedly also produced the B-side. It should be noted, though, that an official announcement confirming this hasn’t been made yet. Though as random as it might be, we know that Grohl is a fan of the mysterious Swedish band (hence the t-shirt he’s been spotted in). Plus, at this point it would come as more of a surprise to hear Grohl doing something uncool.
