Doctors aren’t concerned about the health condition of French-Armenian chansionner Charles Aznavour, who was hospitalized in Saint Petersburg yesterday, reported tass.ru, citing the artist’s insider.

“During a rehearsal for his concert, the maestro had a stiff back, and this is why we had to cancel the concert. Doctors checked Aznavour and confirmed that it was just a muscular spasm. So, there is nothing serious. He is relaxing at the hotel,” reported the insider.

It was announced that the concert in Saint Petersburg has been postponed for April 2019.

However, the 93-year-old chansionner’s official representative Vincens Stark added that Aznavour will return to France on 26 April.
