Pop-Punk sweethearts Fall Out Boy are officially back for a reunion of sorts after going on hiatus in November 2009.  After much speculation, Pete Wentz, Patrick Stump and the rest of the boys have confirmed the rumors by releasing a new single, album and official tour dates.

The comeback package comes complete with the Chicago group's first new music, "My Songs Know What You Did in the Dark (Light Em Up)," since 2009 when they released a Greatest Hits compilation that came with one new song, "Alpha Dog."

Fall Out Boy also released a music video for the new single, which was shot at the site of the original Comiskey Park, the location of the infamous Disco Demolition Night in 1979.

"My Songs" is the first single from Fall Out Boy's forthcoming fifth studio record, “Save Rock and Roll,” due out May 7.

The record also marks the 10th anniversary of the band's debut full length, “Take This to Your Grave.” It will be their first LP since 2008's “Folie a Deux.”

Fall Out Boy’s hiatus saw a solo effort from Patrick Stump, whose 2011 solo debut, “Soul Punk,” fell short of any expectations the singer might have had for himself. Meanwhile, Pete Wentz kept busy with his electropop project Black Cards.

Completing the Fall Out Boy reunion package is a brand new set of tour dates that kick off this May. The tour will come after the group plays a series of shotgun warm up gigs in Chicago tonight, Webster Hall in New York on Tuesday and Los Angeles' Roxy on Thursday. Fall Out Boy will kick off the Save Rock and Roll tour on May 14 in Milwaukee.. Full tour dates are below. For more information, visit Fall Out Boy's website.
