As a preview to the annual Download Festival Olly Barnes takes us back 30 years to the Friday Rock Show from 21st August 1987 when Tommy Vance previews the Monsters Of Rock festival at Donington that year.

Tommy interviews the late, great Ronnie James Dio who appeared on the bill alongside W.A.S.P., Anthrax, Metallica, Cinderella and headliners Bon Jovi. Music from all of the above.
