Legendary singer Lata Mangeshkar herself has praised an auto-rickshaw driver from Karachi for his sweet voice. Master Aslam is on cloud nine after Mangeshkar complimented him for singing a Bade Ghulam Ali Khan 'thumri' with sheer purity."When I heard about it, it brought tears to my eyes. I can't thank her enough," Master Alam said to the daily. In 1993, he took part in a TV programme and reached the grand finale of the talent show.
