LONDON: Rock star Bono of U2 inadvertently leaked songs from his new album when he sang aloud in his villa in South France and a fan walking past his house overheard him and recorded it. The fan then posted the songs on YouTube, reports thesun.co.uk. Daniel Lanois, who has worked with the band in the past, says this is the best work he has done with them. He said, “I think we can safely say it’s one of the great, innovative records from U2. Bono’s in great form, singing fantastic.”
