Noorjehan or Noorjehan (Punjabi, Urdu: نور جہاں) was the adopted stage name for Allah Wasai (September 21, 1926 – December 23, 2000) who was a legendary singer and actress in British India and Pakistan. Her career spanned seven decades. She was renowned as one of the greatest and most influential singers of her time in South Asia and was given the honorific title of Malika-e-Tarannum (Urdu: ملکہ ترنم, English: the queen of melody).

Born in a Punjabi family of musicians, Wasai was pushed by her parents to follow in their musical footsteps and become a singer but she was more interested in acting in films and graced the earliest Pakistani films with her performances. She holds a remarkable record of 10,000 songs to her singing credits in various languages of India and Pakistan including Urdu, Hindi, Punjabi and Sindhi languages. Along with Ahmed Rushdi, she holds the highest record of film songs in the history of Pakistani cinema. She is also considered to be the first female Pakistani film director.

Mehdi Hassan Khan (Urdu: مہدی حسن خان ) is a Pakistani ghazal singer and a former playback singer for Lollywood. He is famously known as the 'King of ghazal' (Urdu: شہنشاہِ غزل). He has ruled the Pakistan film industry along with Ahmed Rushdi. He was honoured with Tamgha-e-Imtiaz, Pride of Performance and Hilal-e-Imtiaz by the Government of Pakistan, and Gorkha Dakshina Bahu by the Government of Nepal.

Mehdi Hassan was born on 18 July 1934 in a village called Luna in Rajasthan, India into a family of traditional musicians. He claims to be the 16th generation of hereditary musicians hailing from the Kalawant clan of musicians. Mehdi Hassan had his musical grooming from his father Ustad Azeem Khan and uncle Ustad Ismail Khan who were both traditional Dhrupad singers. Hassan started to perform at a young age and the first concert of dhrupad and kheyal with his elder brother is reported to have been held in Fazilka Bungla, near present DC House (1935) of Undivided Punjab. After the Partition of India, 20-year-old Hassan and his family migrated to Pakistan and suffered severe financial hardships.
