Opera singer Luciano Pavarotti and U2 star Bono are teaming up for a charity concert to raise money for Iraqi civilians affected by war.
Pavarotti has received an award for services to refugees
The pair will appear together at the 10th annual Pavarotti and Friends charity concert in the tenor's home town of Modena, Italy, in May.
The funds will go to the UN High Commission
for Refugees (UNHCR), which is preparing for a refugee crisis in the Middle East.
The opera star has been joined by big names including Bryan Adams, Liza Minnelli and Elton John for past televised extravaganzas.
This year's concert will take place on 27 May.
In 2002, he was joined by stars including Sting, Lou Reed and Andrea Bocelli for a show to raise money for Angolan refugees.
The previous year, the Pavarotti and Friends concert and related activities raised $3.3m (£2.1m) for Afghan refugees, while $1m (£645,000) was raised for refugees from Kosovo in 1999.
Bono met President Bush in 2002
Pavarotti was awarded the top global award for services to refugees, the Nansen Refugee Award, in 2001.
He first sang with Bono to raise money for victims of the Bosnian war in 1995.
Bono has also been a high-profile campaigner for charity and justice around the world.
He has met President George Bush and French President Jacques Chirac to encourage them to contribute more aid relief to developing countries.
