Green Day races through “Good Riddance (Time of Your Life)” because of Storm

Whether it’s raining or shining, the members of Green Day do everything they can to give their fans the time of their lives!

When the band — drummer Tré Cool, bassist Mike Dirnt and frontman Billie Joe Armstrong — took the stage for an encore during The Saviors tour stop in St. Louis on Thursday, August 15, rain began to fall, forcing them to speed through their final song.

As usual, the rockers closed the show with their hit “Good Riddance (Time of Your Life),” but this time they played a sped-up version of the song to finish before a storm hit the Hollywood Casino Amphitheater, as footage captured by fans shows.

After telling his fans “we need to get you out of here because there’s a big storm coming” – and thanking them, of course – the 52-year-old Armstrong launched into an extremely fast and completely acoustic rendition of the 1997 hit.

“Another turning point, a fork in the road / Time grabs you by the wrist and shows you the way,” he sang in a much higher pitch – and faster speed – than his usual singing voice.

The Green Day singer continued singing as the crowd streamed out of the amphitheater, stopping every now and then to say things like “keep walking” or gesture toward the exit.

“I hope you had the time of your life,” Armstrong concluded, as Cool, 51, and Dirnt, 52, flanked him on either side to say a final “thank you” to their fans.

Green Day’s Saviors Tour, which began in May, is a major celebration of two milestones – the 30th anniversary of the band’s 1994 album Dookie and the 20th anniversary of their 2004 LP, American Idiot — also the release of the band’s 14th studio album, savior.

In North America, the tour featured opening acts The Smashing Pumpkins, Rancid and The Linda Lindas, while in the UK and Europe, Nothing But Thieves, The Hives, Donots, The Interrupters and Maid of Ace opened for the band.

Speaking to PEOPLE ahead of the tour, Armstrong explained the significance of several of the band’s classics, including the classic “Good Riddance (Time of Your Life).”

“I had my first real girlfriend and she went to Cal (University of California, Berkeley). Me and Tré and a couple of other guys lived in this house on Ashby Avenue and she and her roommates lived above us,” he recalled. “I remember going to this party one night and listening to these college kids playing these acoustic songs and I was like, ‘Oh wow, this is pretty cool.'”

“She moved to Ecuador and I was pretty heartbroken about it, so I wrote this song (from 1997 Nimrod) for her,” Armstrong continued. “It’s a simple love song on the guitar and it ended up being played at graduations and bar mitzvahs; at funerals and weddings.”

“It’s wild what it turned out to be,” he added of the track.
