Four top musicians are teaming up next week to record a charity song, Classic Rock Magazine reported.

Tony Iommi, Ian Gillan, Jon Lord and Nicko McBrain will be in the studio, doing an undisclosed tune, the idea being to use the money to help rebuild a music school in Armenia.

This isn’t the first time Iommi and Gillan have done something for Armenia. In 1989, the pair, together with a number of other high profile names, recorded a version of Smoke On The Water, to help victims of the devastating 1988 earthquake. That was under the name Rock Aid Armenia.
