NEW YORK, June 22 -- MTV and VH1 will telecast eight hours of the Live 8 concerts July 2, the networks said Wednesday.

The performances, featuring U2, Coldplay, Madonna, the Dave Matthews Band, Jay-Z and Destiny's Child among many others, are being held in eight cities to raise awareness of poverty in Africa.

The telecast is a repeat performance for MTV, which telecast the Live Aid concerts two decades ago. Like Live Aid, the Live 8 performances are being organized by Bob Geldof.

America Online, which owns the U.S. rights to the concerts and will beam them on the Internet, also is negotiating with ABC for a prime-time telecast July 2 after the cable TV coverage.

MTV, VH1 and mtvU, MTV's college network, will be on the air with the same feed from noon to 8 p.m. that day, rotating among the different sites and also presenting packaged reports, such as a look back at Live Aid.

Related networks CMT and VH1 Classic will air concert highlights the next day featuring artists geared to their audiences.

It will be the longest period MTV has gone live to cover an event since Woodstock '99, the network said.

XM Satellite Radio will carry the concerts live from Philadelphia, London, Paris, Berlin and Rome, America Online also said Wednesday. The other venues are Toronto, Tokyo and Johannesburg.

Bono and U2 are among the acts performing in eight cities July 2.
