A extremely popular qawwali by Ustad Nusrat Fateh Ali Khan - Allah Hoo Allah Hoo. This qawwali has been played on the harmonium (vaja) by Mamo accompanied with Tabla and is mostly improvised. This is a sufi qawwali chanting the name of God and was a signature qawwali of Nusrat Saab. This composition was commposed by Nusrat Saab and his brother Farrukh Fateh Ali Khan who played the harmonium and gave that edge to their qawaali's by playing the harmonium so beautifully. Farrukh Fateh Ali Khan was so underestimated due to being the younger sibling of Nusrat Saab. Other members of the qawwal party included, Rehmat Ali, Maqsood Hussain, Rahat Nusrat Fateh Ali Khan, Dildar Hussain, Majawar Abbas, Mohammed Iqbal Naqvi, Asad Ali, Ghulam Farid and Kaukab Ali.
