Fun. Dump The 'Colbert Bump' Ahead Of StePhest Colbchella '012

'It sounds like you're going to do coke with Stephen Colbert,' Jack Antonoff says of the phenomenon that yields spikes in popularity.

Fun. are ardent supporters of marriage equality and LGBT rights, which is why it's odd that they've chosen to align themselves with Comedy Central's foremost conservative voice, Stephen Colbert, by performing at Friday's StePhest Colbchella '012: RocktAugustFest.

They'll be joined aboard the U.S.S. Intrepid by fellow musical acts Santigold, the Flaming Lips, Grizzly Bear and "official Colbchella aircraft carrier-based DJ" Grandmaster Flash. And though they may be at odds with Colbert's right-leaning views, they signed on for Colbchella anyway ... mostly because they want to smash the system from the inside, man.

"We just do what our peers do, so when we saw that the Flaming Lips were doing it, we put politics aside and thought, 'This is really, really cool,' " frontman Nate Ruess told MTV News backstage at Lollapalooza. "Same thing with [playing this festival]; I don't think people realize the cruel things they do to infants."

"They have infants making Chick-fil-A sandwiches right here at Lollapalooza," guitarist Jack Antonoff added. "And Stephen Colbert is a part of that, so the fact is, we feel like we could make a bigger dent from the inside out."

And to that end, Fun. are downplaying any and all benefits of appearing at Colbchella '012 ... including the much-vaunted "Colbert Bump" phenomenon that would almost certainly send their album sales skyrocketing. Mostly because they weren't aware such a thing even existed until we told them about it.

"Is that a real thing?" Antonoff asked. "It sounds like you're going to do coke with Stephen Colbert."

Instead, they'd prefer "A Glenn Beck Dip" (as Ruess put it), or perhaps some slightly more salacious perks.

"I'd rather have some of the Rush Limbaugh Vicodins," multi-instrumentalist Andrew Dost laughed.

"I would love it if Bill O'Reilly would put a loofah all over my body," Antonoff added.

Then again, until Rush or Bill O decide to throw their own music fests, it seems that Fun. might have to make do with an old-fashioned Colbert Bump ... whether they want it, or not.
