An Armenian group will play his rock ballad, 'Lonely Planet.'

Tony Iommi has written a rock ballad for the Eurovision Song Contest.

According to the BBC, the Black Sabbath guitarist contributed the unlikely song to the Armenian group Dorians after making a connection with the country years ago. In 1988, he helped produce a fundraising album in the wake of an earthquake that left half a million people homeless. He's since returned to Armenia with Queen's Brian May to check in and raise additional funds.

So when the call came to help out with the annual contest, he went for it, passing along the song "Lonely Planet."

"I first said, 'oh God, I don't know' - it seemed really strange, me doing a Eurovision song, I don't usually do that," he told the BBC. "But I said, 'I've got a rock ballad, I'll send it over."

The contest will run three nights in Sweden, concluding on May 18. 

Iommi continues to undergo treatment for lymphoma, an illness he announced last year. In better news, he's also been at work on Black Sabbath's new album, "13." The set, recorded in Los Angeles with Rick Rubin, is expected later this year.
