First Iron Maiden singer Paul Di'Anno will perform with three other former members of the band for a one-time-only concert this summer, at Worcestershire, England's Beermageddon Festival 2020 on Sunday, Aug. 30. It will be Di'Anno's "final ever" performance following the musician's recent health issues, and he will sing next to the classic Maiden members. They will come out to the stage under the Ides of March moniker.
