The concert venue is the “Palazzetto dello Sport”, in Mestre, the mainland to which Venice is connected by a bridge, part of the same city. It is now named after a victim of the Red Brigades, Giuseppe Taliercio, who was killed in 1981. Online, the concert is sometimes listed as held in the “Palazzetto Taliercio” but it was just “Palazzetto dello Sport” in 1980.
Thanks for that information, Lello. I have updated the concert info. Grazie.
