In case you haven't yet heard Weezer's latest comeback single, you're about to get your fill over the next couple months. The veteran alt-rock band is kicking into the promo cycle for upcoming LP "Everything Will Be Alright in the End," and they gave lead single "Back to the Shack" its debut television performance last night on "Fallon."

In the incredibly self-referential song, frontman Rivers Cuomo name drops his trademark lightning bolt guitar strap (which he's of course wearing), drummer Pat Wilson, and the good old days of 1994. Cuomo does plenty of gang harmonizing with guitarist Brian Bell and bassist Scott Shriner, delivering a tight studio performance of the track that Weezer has been playing live over the past few months.

Watch until the very end to see Jimmy Fallon get (understandably) a little fan-boyish at the conclusion.

"Everything Will Be Alright in the End" drops Sept. 30 via Republic. It was produced by Cars frontman Ric Ocasek, the same Ric Ocasek who helmed Weezer's "Blue" and "Green" albums.
