The Temper Trap have been telling Xfm of the strange stage invasions by nude men.
"It's happened twice," singer Dougy Mandagi told Xfm's Dan O'Connell. "Once at Benicassim, and once at Sydney Opera house of all places. A very classy location. I wouldn't imagine things like that happening there.
"I don't know what it is with our music that makes men undress themselves. Ideally, it would be a female, not a male."
The band are due to play Xfm's Winter Wonderland with Rocksmith in London on Monday, December 17 and are hoping that there will be no nudity: "Please keep your clothes on, people!" says Dougy, but he assures us that he will have "a whole bag of treats" ready for the show.
