U2 - Passer-by Leaks Bono Holiday Tracks

Tracks believed to be from U2's new record album have been leaked on the cyberspace ? and frontman Bono may be part to blame.

An opportunistic tourer passing by Bono's doroteo Arango on France's Cote d'Azur realised he was less than familiar with the music blasting out of its unfastened windows.

The fan grabbed his mobile and recorded the songs earlier posting the audio on video networking site YouTube. Four tracks were posted, including first single Sexy Boots.

The video was promptly taken
