Look out for headbanging, heavy metal heroes in Gloucestershire today
A string of heavy metal musicians will be paying tribute to Cirencester-born, drummer Cozy Powell who worked with both bands.
It follows a Cozy Powell tribute concert in December where a host of 1970s stars appeared to remember the late chart-topping drummer who was killed in a crash.
It raised over £4,500 which will be handed over to the late star's favourite charity, World Animal Protection.
The cheque will be handed over at the Corn Hall in Cirencester which has a plaque dedicated to Cozy who died in a car crash on the M4 in 1998, aged 50.
Man and Asia drummer Bob Richards and musicians Ian Richard Wills and Esther Rowley will also be there.
The tribute for Cozy concert was held on December 29 and featured the original kit used by the influential drummer who appeared on at least 66 albums with bands including Rainbow, Whitesnake, Black Sabbath and The Jeff Beck Group.
Musicians who put in an appearance on the night included Uriah Heep's Russell Gilbrook, Cats in Space frontman Paul Manzi, Mike Terrana, The Sweet's Tony O'Hora, Thunder's Chris Childs and Harry James, Michael Schenker group members Chris Glen and Ted McKenna, Dare guitarist Vinny Burns and Lionheart's Lee Small.
In 2016 Queen guitarist Brian May unveiled the plaque at a ceremony attended by Suzi Quatro, Tony Iommi, Neil Murray and Bernie Marsden, leading to speculation that Murray and Iommi , who lives on the Gloucestershire borders, would perform together again.
Mr May said his friend was "one of the world's most exciting drummers ever" who set the "heavy drummer template."
"Cozy was always a West Country boy... he never lost his way of speaking and he never lost his attachment to the land," he said of his friend who started performing in his home town with The Corals in the 1960s.
Born Colin Flukes, he changed his name and had three Top 20 hits in 1973 - charting number three under his own name with Dance with the Devil.
