VIENNA (AP) — Placido Domingo is scheduled to sing two concert performances in Verdi’s “I Vespri Siciliani (The Sicilian Vespers)” next summer as part of the 100th anniversary Salzburg Festival, which features 221 performances over 44 days and includes seven staged operas.

Domingo, who turns 79 in January, was dropped or has withdrawn from all his U.S. performances since reports by The Associated Press in August and September detailed accusations against him of sexual harassment or other inappropriate, sexually charged conduct.

He received standing ovations in Salzburg at performances of Verdi’s “Luisa Miller” last August and is welcome back pending investigations by the LA Opera, where he resigned as general director last month, and the American Guild of Musical Artists. Helga Rabl-Stadler, president of the Salzburg Festival, said Domingo was engaged two years ago to sing the baritone role of Guido di Montforte on Aug. 16 and 19. European houses have maintained Domingo’s contracts.

“We do not see any reason why we should change our opinion if there are no new facts,” Rabl-Stadler said in a telephone interview.
