The upcoming musical concert by legendary Saudi singer Muhammad Abdu, which was scheduled for Sept. 22 in Jeddah, has been postponed until further notice, Al-Riyadh reported. Sources said that the singer preferred to delay the concert until he completed his medical treatment. The new date of the concert will be announced later. The singer arrived in Jeddah early August after he spent more than two months in France receiving treatment for a heart attack. Abdu suffered from a cardiac arrest and was rushed to France for treatment. He was allowed to return to the Kingdom after he fully recovered from his illness.
