People who have been fans of this band for years may never have heard either of these two guys sing into the microphone as much (or, uh, as tunefully) as they do here–it’s pretty much the exact opposite of whatever bad PA yelling they do out at Brooklyn or the Mercury Lounge, etc. Fallon looks impressed, although then again, he always sort of does. Questlove would’ve preferred “I Quit Girls” but otherwise seems pretty thrilled. This was their television debut, according to Jimmy. Still can’t believe they skipped “Young Hearts Spark Fire” but otherwise, they certainly looked like they belonged out there. Next up? A haircut, hopefully.
