Jussi Bjorling life, heart condition
The excitement was palpable that evening, May 20, 1958, at the Royal Theatre in Stockholm. The two Swedish opera giants, Birgit Nilsson and Jussi Bjorling, would again meet al the Stockholm Opers in Tosca. The theatre was crowded, and the press present- for tonight's performance could not be anything but magnificent. But already in the first act, something happens. Bjorling cannot sustain the tone. He can only whisper per the lyrics. He had suffered one of his recurring vocal cord problems.
