U2 Free iTunes Song 'Invisible' Super Bowl Ad

U2 and Bank of America will combine in a charitable fundraising effort that kicks off during the Big Game on Feb. 2. The 60-second Super Bowl ad will feature U2 singing and will invite viewers to download a limited edition of the song on iTunes.

The download will be free during the game and for the following 24 hours. During that time, Bank of America will donate $1 for every download — up to $2 million — to the Global Fund to Fight AIDS, Tuberculosis and Malaria.

U2 frontman Bono made the announcement with Bank of America CEO Brian Moynihan at the World Economic Forum in Davos, Switzerland.
