Jay-Z and U2 record a duet for Haiti

Jay-Z and U2 have recorded a duet to raise money for charity.

The '99 Problems' rapper and the legendary Irish rockers have joined together to collaborate on a single with the help of producer Swizz Beatz to generate funds for victims of the devastating earthquakes in Haiti.

U2 rocker The Edge – who is joined by Bono, Adam Clayton and Larry Mullen Jr. in the band – revealed on Irish radio station 2FM: "Bono got a call from a producer, Swizz. He and Jay-Z wanted to do something for Haiti. So Bono came up with a phrase on the phone and last night we were here, we wrote a song, finished, recorded, and sent it back to them.

"So, that might be the next thing you hear from us."

Meanwhile, 31-year-old producer Swizz has the promised the track he made with the band and the rapper – who is known to friends as Hova - will be "amazing".

He tweeted: "Me, Bono, Hova have something to say about Haiti. Stay tuned.

"I told you I was working on something amazing for Haiti. They need us!"

The release date is not yet known.

In the meantime, some of the world's biggest musicians are preparing to perform at an international Haiti telethon on Friday evening (22.01.10) to help raise funds.

Coldplay and Jay-Z have been confirmed to perform at a London location, while Kid Rock, Sheryl Crow and Keith Urban will all sing in Los Angeles.

Haitian-born singer Wyclef Jean – who has led a money-raising appeal for the cause – will perform in New York alongside Mary J Blige, Shakira, Sting and Bruce Springsteen.

The Caribbean nation has suffered another devastating earthquake today (20.01.10), while the area is still recovering from last week's first natural disaster.
