During a stop on her A Matter of Time tour, Icelandic artist Laufey delighted her Arizona audience with an unexpected guest: Benson Boone. Together, they performed a beautifully tender duet of “Somethin’ Stupid,” the classic Frank & Nancy Sinatra song, turning it into a magical highlight of the night.

The concert at Desert Diamond Arena in Glendale featured Laufey’s signature “surprise song” segment. She called out to the crowd asking if Benson Boone was in the house, and moments later, he stepped onto the stage. The audience erupted as the two artists began trading lines and harmonizing, delivering a rendition that felt both intimate and timeless.
