Black Sabbath members to form new band

LOS ANGELES - The Black Sabbath boys are back, as the new band Heaven and Hell. Guitarist Tony Iommi, bassist Geezer Butler, drummer Bill Ward and singer Ronnie James Dio former members of British metal supergroup Black Sabbath are forming the band named after their 1980 hit, according to their publicist. They plan to launch an international tour next year.

"The fans have been wanting to see this for years and years. Now was just the time," publicist Maureen O'Connor said Wednesday.

Since its formation in 1969, Black Sabbath has undergone numerous member changes and reunions.

Dio, who replaced original Sabbath vocalist Ozzy Osbourne as part of the band's early '80s lineup, has been recording new songs with Iommi in England, O'Connor said.
Interesting news. Looks like the second incarnation of the band may be back with a vengeance, which would be nice in an era where Ozzy has become little more than a reality TV joke.
