William Beckett Joins Fall Out Boy To Perform ‘Slow Down’ at Madison Square Garden: WATCH

Fall Out Boy surprised fans with special guest William Beckett to give an epic performance of “Slow Down.”

On Friday (March 22), the band stopped at New York City’s Madison Square Garden as part of their So Much For Stardust 2our. During the tour, the band has a Magic 8 Ball that comes on screen that will choose a surprise song that the band will then perform live. For this show, “Get Busy Living or Get Busy Dying (Do Your Part to Save the Scene and Stop Going to Shows)” was the first song that the mystical ball selected. This marked the band’s first full performance of the song, ever.

However, after the song, bassist Pete Wentz asked the crowd if they wanted the night to end. He then asked the crowd, “Should we just f—ing slow down?”. The Magic 8 Ball on screen responded, “All signs point to yes.” The lights went out and a moment later they returned, this time, with The Academy Is… front man William Beckett on stage. The crowd went wild and were mesmerized by the band’s cover of The Academy Is… classic.

Watch the full performance of “Slow Down” with Fall Out Boy and The Academy Is… William Beckett, below.

‘Slow Down’ By Fall Out Boy and William Beckett

Fall Out Boy and William Beckett, front man of The Academy Is…, have frequently worked together over the years. The band and now solo singer both got their starts in the Chicago music scene and rose to fame in the mid-2000s.

You’ll recall that Beckett provided backing vocals on the band’s 2005 track, “Sophomore Slump or Comeback of the Year.” The bands frequently crossed paths touring together and playing numerous festivals on the same bills. Then in 2008, Beckett was featured on their track, “What a Catch, Donnie.”
