The Pixies are currently in the throes of the North American leg of their Doolittle tour, a wormhole of a trek we've been quick to spill much digi-ink over in these parts recently. Via an e-mail from the band's publicist, we've just learned that the band will sandwich in an appearance on Late Night with Jimmy Fallon next week when they come to New York for four sold-out nights at Hammerstein Ballroom. So if watching Fallon get goofy is your thing, check your DVR of tonight's show come tomorrow morning. He's planning to announce the following: while The Pixies will be kicking things off with "Debaser," fans/you guys now have the opportunity to choose their Doolittle second jam via Twitter. Fire those in Fallon's direction (@jimmyfallon) and maybe make it "Hey." Just an idea.
