Q's tribute to U2, AHK-Toong BAY-Bi Covered was released along with the October 26th edition of the magazine in the U.K. The compilation features covers from Nine Inch Nails, Garbage, The Killers, Jack White, and more. For fans outside the U.K. who couldn't snag their own copy of Q, U2 has been selling physical copies on their website, and now it looks like the digital version is now available on iTunes. Note that you cannot purchase single tracks, only the album as a whole, and all of the proceeds from the album sales go to the charity Concern Worldwide.
