Just days after rehearsing their breakthrough 1994 album Dookie in its entirety and posting about it on social media, the men of Green Day returned to their practice room, this time to apparently play Dookie's 1995 follow-up, Insomniac, in full as well. This time it was bassist Mike Dirnt who posted a photo of the band and told fans to swipe if they wanted to see the set list, which was all of Insomniac.

Drummer Tre Cool did the same thing earlier in the week, letting fans know that the trio had rehearsed Dookie from start to finish.

Fans are now theorizing that instead of embarking on a 25th anniversary Dookie tour as initially speculated, Green Day may play both Dookie and Insomniac back to back each night or alternate between the two albums from show to show.

Dirnt told us not long ago that playing a whole album in the middle of a live set is not out of the question for Green Day: "We try to keep it fun for ourselves, you know. We'll mix it up if we feel like it's getting too -- you know, we don't want to ever going through the motions ever, either, so you know, we won't do it. We'll stop in the middle of a set and go, 'You know what? We're gonna play Dookie in its entirety.' But you know, we just keep it fun. It definitely is a good problem to have, to have such a big discography."

Insomniac was Green Day's fourth studio LP and featured a heavier sound than Dookie. It included the singles "Geek Stink Breath," "Brain Stew/Jaded" and "Stuck With Me." While not as massive a seller as Dookie, it still moved over two million copies in the U.S.
