This has come from Blabbermouth (thanks Jerr), however please note that as of yet Channel 4 have not confirmed this!

BLACK SABBATH guitarist Tony Iommi's official web site has been updated with the following message:

"The new series of 'Rock School' presented by [KISS bassist/vocalist] Gene Simmons takes to the screens in the U.K. on Sunday 29th January, and features Tony in the second episode which goes out on 5th February at 9:00 p.m. on Channel 4. Tony took over the teacher role for an afternoon and gave the kids an in-depth masterclass in the art of the guitar where he shared some of his tricks of the trade and his rock and roll anecdotes. The programme was recorded in autumn 2005 at Kirkley High School in Lowestoft (home of THE DARKNESS) and is the second in the 'Rock School' series produced by RDF Media."
