Grouplove's fabulous summer jam "Tongue Tied" has been all over the place in the last few months, from an iPod Touch commercial to late-night TV to cars with windows rolled down. (If you haven't heard it and your musical tastes fall anywhere near the intersection of Arcade Fire and Mumford And Sons, it's well worth a listen.) We were delighted both that the sunny band chose Andrew W.K.'s party anthem "Party Hard" and that they brought some props. You'll see what I mean. Revel in the mellowness.
