The song Black Sabbath's Tony Iommi co-wrote for this year's Eurovision Song Contest has surfaced online. 

A video for the song "Lonely Planet" performed by the Armenian band Dorians has been posted on YouTube. 

Iommi tells Classic Rock magazine he's "really pleased how it turned out," and adds that he has his "fingers crossed" for the competition. 

Iommi teamed up with lyricist Vardan Zadoyan to pen "Lonely Planet," which the guitarist has described as a "rock ballad."  Dorians will perform the song in the Eurovision semi-finals in Sweden next month.
