Named on the cast sheet distributed with the in-house recording of the Opera Nationala Bucuresti Il trovatore of Friday 13 April 2007 (in the rip as "Il Trovatore - 2007.04.13 (Papa, Saplacan, Basalic, Colpos c Florea, Bucharest).txt"). The house has no online performance archive, so that sheet is the only document naming this cast; the house does document the night itself -- its April-June 2007 repertoire leaflet, http://web.archive.org/web/20070221140435/http://www.operanb.ro/downloads/apr-iun.pdf, prints "APRILIE / Vineri 13, ora 18.30 / IL TROVATORE", and its live calendar as captured on 8 April 2007 shows "Il Trovatore (18:30)" on 13 April. Romanian Wikipedia names an Adriana Alexandru among the singers in the Vasile Martinoiu article, alongside Iordache Basalic of this same cast.
