Legendary Singer Mehdi Hassan is being used by some companies to promote their products. The singer is in poor health and showing him with tears in his eyes speak of the insensitivity on part of the companies using his agony for their economic benefits. More importantly, how much is he getting paid for he needs financial assistance more then his personal personification. Most likely a meagre amount would have been paid to him instead of paying him a percentage of the revenues earned through these advertisements. Let us not "use" him for monetary gains and instead do something useful for the deserving artist. DR. IRFAN ZAFAR, Islamabad, May 30.
