An Adam Lambert and Queen concert is already a major event, but Sydney Queen fans got the shock of their lives when none other than Lady Gaga crashed the English rockers’ show to sing “Another One Bites the Dust”! Lambert opened up the 1980 number one hit with a fiery vocal, before Gaga appeared to sing the second verse with incredible energy and swag.

Gaga hit the stage in an outlandish teased black wig that added half a foot to her height, presumably in tribute to Cher’s iconic 1980s hairstyle. This seemed to make the audience not recognize Gaga at first, but when Lambert introduced her by name the crowd lost it. Lambert and Gaga then traded lines, and the energy they put out while they fed off each other’s vibe was really something. This performance has gone a bit under the radar on YouTube so far, but The Music Man readers will find a whole lot to enjoy here.

Gaga made her surprise appearance at Queen’s show in Sydney, Australia, on August 27, 2014. The Music Man readers will definitely want to tune into the section just after the two-minute mark, when Lambert and Gaga make their way to the walkway at the front of the stage and trade lines while getting up close and personal with the audience.

Queen have created a number of incredible live features over the years, with not only their own songs but also a cover or two at times. One particularly memorable moment featured guitarist Brian May and drummer Roger Taylor sharing lead vocals with Bad Company singer Paul Rodgers on John Lennon’s “Imagine.” The vocal line in Queen really is amazing, with the band’s backing singers like May and Taylor having simply sublime voices as well.

Queen dropped “Another One Bites the Dust” on August 22, 1980, as the fourth single from their eighth studio album, The Game. The funk rock banger quickly became a worldwide hit and topped the Billboard Hot 100 for three weeks. The song is Queen’s highest-selling single, as it shifted seven million units, and ranked at number 34 on the Billboard All-time Top Songs list. Queen bassist John Deacon wrote “Another One Bites the Dust” in one of his most significant contributions to the Queen discography. The song is one of only three Queen songs to surpass two billion streams on Spotify, where it is placed third behind “Don’t Stop Me Now” and “Bohemian Rhapsody.”
