The Scissor Sisters will play one of their biggest headlining shows in the United Kingdom as part of a Sept. 16 AIDS benefit at London's Trafalgar Square. Proceeds from ticket sales will go to RED, the anti-AIDS campaign co-founded by U2 frontman Bono.

The event will promote the release of the band's second album, "Ta-dah," which includes the Elton John-featuring single "I Don't Feel Like Dancing." Scissor Sisters' self-titled debut was the U.K.'s biggest selling title in 2004, according to the Official U.K. Charts Company.

The Trafalgar Square concert is a joint project with U.S. wireless carrier Motorola, which is using the event to promote its red-colored MOTOSLVR handset. Tickets are free but only available for 10 days beginning today (Aug. 18). Fans must text the word "MOTORED" to the number 80855 at a cost of $2.80.

"London is our spiritual home, and the U.K. gave us our first and longest-lasting embrace," group member Babydaddy told the media. "To be able to play this event in conjunction with the [RED] campaign and to launch our new album seemed the perfect match."

Motorola and its U.K. retail partners are also contributing $18.90 to the Global Fund from every sold MOTOSLVR device, which launched on May 15. U.K. mobile networks are donating 5% of the monthly bill generated via MOTOSLVR handsets to the fund.
