Waheeda Rehman (born14 May 1936), is an Indian film actress who appears in Bollywood movies and is known for many successful and critically acclaimed movies from 1950's, 60's and early 70's most notably C.I.D. (1956) and Guru Dutt classics such as Pyaasa (1957), 12 O'Clock (1958), Kaagaz Ke Phool (1959), Sahib Bibi Aur Ghulam. Her other notable works include Solva Saal (1958), Baat Ek Raat Ki (1962), Kohra (1964), Guide (1965), Teesri Kasam (1966), Aadmi and Khamoshi (1969).

One of the most prominent actresses of the golden era, Waheeda Rehman was born into a traditional Telugu-speaking Muslim family in Chengalpattu, Tamil Nadu, British India. She and her sister learnt Bharatnatyam at Mumbai's Sri Rajarajeswari Bharata Natya Kala Mandir, where Guru T. K. Mahalingam Pillai, doyen among nattuvanars taught and performed on stage together. Her father, who was a District Commissioner, died while she was still in her teens.

It is a common misconception that Rehman was born in Hyderabad. “It’s a long story,” she says, “When I was in Chennai, I did three to four Tamil and Telugu movies. In the first one, Kaalam Maari Pochu along with Gemini Ganesan a bilingual film which was made in Tamil and Telugu as Rojulu Maraayi, I did only a folk dance number in both Tamil and Telugu versions. However, it went on to become a hit! I was in Hyderabad celebrating its success and Guru Dutt happened to be there. He was on a lookout for new faces and heard that I could speak in Urdu. It is because he spotted me in Hyderabad that people assume I was born there.”

Lata Mangeshkar (born September 28, 1929) is a singer from India. She is one of the best-known and most respected playback singers in India. Mangeshkar's career started in 1942 and has spanned over six and a half decades. She has recorded songs for over a thousand Hindi films and has sung songs in over thirty-six regional Indian languages and foreign languages, though primarily in Hindi. She is the elder sister of singer Asha Bhosle, Hridayanath Mangeshkar, Usha Mangeshkar and Meena Mangeshkar. She is the second vocalist to have ever been awarded the Bharat Ratna, India's highest civilian honour.

Mangeshkar was featured in the Guinness Book of World Records from 1974 to 1991 for having made the most recordings in the world. The claim was that she had recorded approximately 25,000 solo, duet, and chorus-backed songs in 20 Indian languages between 1948 to 1974. Over the years, while several sources have supported this claim, others have raised concerns over its veracity, claiming that this number was highly exaggerated and that Mangeshkar's younger sister, Asha Bhosle, had more song recordings than she had. In 2011 Guinness officially acknowledged Bhosle as the most recorded artist in music history.
