Italian film-composing legend Ennio Morricone’s ongoing health concerns have led to the cancellation of his three North American concerts in June, sources say.

Morricone, who suffered a back injury earlier this year that led to the postponement of his scheduled March concerts in New York and L.A., had been slated to conduct his own 100-piece orchestra on June 13 (in Brooklyn), June 15 (at LA Live’s Nokia Theatre) and June 18 (in Mexico City).

Members of the 75-voice choir that had been scheduled to accompany the maestro in L.A. were informed Sunday that the concert had been cancelled due to his “serious health issues.”

In addition to his three North American appearances, sources say the rest of his planned concert tour — with 21 dates across Europe from late June through March of next year — is also likely to be cancelled.

Publicists for the Morricone concerts could not immediately be reached.

The 85-year-old composer of “The Mission,” “The Good, the Bad and the Ugly,” “Days of Heaven” and more than 400 other scores has never appeared in concert in Los Angeles. His sole previous American concert was in 2007 in New York.

Morricone is only the second composer in Oscar history to receive an honorary Oscar for career achievement. He received it in 2007. His other notable scores include “Cinema Paradiso,” “Once Upon a Time in America,” “The Untouchables” and “Bugsy.”
