Ghazal King Mehdi Hassan sings Abdul Hameed Adam's ghazal in a unique raag in a mehfil-e-ghazal in Islamabad - 1987 - Mehdi Hassan describes it as the most difficult raag - almost an impossible one! Rarity of this raag is evident from the fact that no one ever tried it during the last about a century. It was only the Ghazal King who accomplished this impossible task!
