U2 frontman Bono sings at Omaha wedding reception for Warren Buffett's granddaughter

OMAHA, Neb. (AP) -- Family connections helped one Omaha couple sign up U2 frontman Bono as their wedding singer last weekend.

Bono took the microphone and sang "Stand By Me" at the reception for billionaire Warren Buffett's granddaughter, Emily Greenberg.

One of the guests at the wedding posted a video of Bono's performance online at http://bit.ly/14yzD9U .

The Omaha World-Herald first reported the Friday night performance before 285 wedding guests. Buffett and his three children, Susie, Howard and Peter, all attended.

The Buffetts and Bono have become close while working on similar philanthropic causes. Susie Buffett serves on the board of the DATA charity Bono co-founded in 2002 to focus on Debt, AIDS, Trade and Africa.
