Like a whisper campaign about a tatted-up unicorn, Blink-182's elusive first reunion single, "Up All Night," has been the subject of chatter for years. The band first started talking about the tune in 2009, when they reunited after a nearly four-year hiatus, but because the recorded version of the song wasn't quite finished at that point, they decided against playing the song live during their subsequent tours.

But now they're ready to pull back the curtain on the song, which is slated to premiere at 10:30 a.m. EST on Friday. The tune will roll out on powerhouse Los Angeles rock station KROQ (106.7 FM) and on the band's official website, according to an announcement posted on the group's official Facebook page.

While recording on the band's first new album since their self-titled 2003 disc was recently wrapped, a release date for the as-yet-untitled CD has not been announced. Blink went on indefinite hiatus in 2005 amid inter-band tensions and announced their reunion at the 2009 Grammy Awards. They then hit the road that summer along with Weezer and Fall Out Boy.

Though they've kept it off the live list for two years, it's likely "Night" will be added to the band's set when they kick off their upcoming Honda Civic-sponsored tour dates with My Chemical Romance on August 5 at the PNC Bank Arts Center in Holmdel, New Jersey. In addition to MCR, the band will be joined by a rotating list of other support acts on the tour, including Manchester Orchestra, Rancid, Against Me! and Matt & Kim.

Bassist Mark Hoppus sounded pumped about the new songs in a recent Facebook post, writing, "Currently listening to THE FIRST MIX FROM THE NEW ALBUM!! Sounds kick. Ass. Cannot wait until this album is released! BOOM!!!"
