While OK Go are the primary players on the new 'Muppets: The Green Album' LP -- having recorded the opening track which just so happens to be the 'Muppet Show Theme Song' and releasing a video for the tune -- they aren't the only star power that the puppets recruited. Weezer and Hayley Williams of Paramore also recorded 'Rainbow Connection' for the album, which is another Muppets classic.

In the song, Weezer frontman and Hayley Williams trade verses on the tune, which was popularized by Kermit the Frog in the 1979 flick 'The Muppet Movie.' As the pair sings, the remaining guys from Weezer play sweet, laid-back music to accompany the contemplative, dreamy lyrics about the finding the magical "rainbow connection." On the third verse, Cuomo and Williams sing together as the beat picks up with drums and more prominent guitar notes.

In addition to Weezer and Williams' 'Rainbow Connection' collabo, the brand-new 'Muppets' album also features a plethora of artists from different genres. Amy Lee of Evanescence takes on 'Halfway Down the Stairs,' the Fray sing the wacky fun-filled 'Mahna Mahna' song, and indie rock outfits My Morning Jacket and Airborne Toxic Event perform 'Our World' and 'Wishing Song,' respectively.

'Muppets: The Green Album' is a musical project designed to get movie-goers and Muppet-lovers psyched for the new Muppets flick that is slated for release this November. The movie, entitled 'The Muppets: Green With Envy,' was c0-written by comedic actor Jason Segel, who is not shy about his obsession with not just the Muppets, but all kinds of puppets. The film also stars Amy Adams and the entire Jim Henson-created puppet crew, and will hit theaters Nov. 23. We cannot wait!
