In the late 1970s, western Disco was getting popular in Asia and in India – but there was no home-bred musician who could belt out a Disco tune or two with ease and authority. it was this reason that led established Indian actor and film-maker Feroze Khan to England and to Biddu, in 1979. Khan wanted to introduce a catchy song in his upcoming Hindi film Qurbani, in which the main score of the film was to be legendary Indian music duo, Kalyanji-Anandji.

It didn't take a long time for Biddu to compose Aap jaisa koi for Qurbani. Critics said Biddu's tune and composition of Aap jaisa koi sounded very similar to the Tina Charles' hit Dance Little Lady Dance. As the girl, Nazia Hassan, had a nasal voice Biddu decided to backtrack it for an echo effect. The song which was recorded in London, was the first Hindi song to be recorded on 24 tracks. In 1980, Qurbani ran to packed houses in India, largely on the weight of Aap jaisa koi and another number Laila O Laila. Nazia Hassan became a teenage sensation. Aap jaisa koi was a massive hit in the subcontinent.

Riding on the massive popularity of the song and the film, Biddu decided to sign Hassan and her brother Zoheb up for a Hindi pop album, something hitherto not tried in India. Biddu modelled them on the then popular American brother-sister duo, The Carpenters. Biddu composed a few catchy numbers for Nazia and Zoheb for the album Disco deewane. In 1981, the album was a massive hit across Asia, South Africa and some countries in South America, charting in 14 countries. The album became the biggest selling pop album in Asia. Nazia Hassan became a household name in the subcontinent. Biddu saw his stars rise in India.

Having spent nearly a decade with this pair, Biddu next turned his attention to Hindi vocalist Shweta Shetty, both writing and producing the Johnny Joker album in 1993. Then in 1995, came another sensational pop album, composed and produced by Biddu. Made in India - a remarkable dance album for Hindi pop/film playback singer Alisha Chinoy. The album became the best selling Hindi dance album ever and featured a slick handful of Western styled videos - a sure selling point for India's newly-launched MTV set.

In 1996, Biddu made a brother-sister duo again with Shaan (Shantanu Mukherjee) and Sagarika Mukherjee, producing the Naujawan album. Biddu spent the rest of the 1990s working with a variety of musicians, including the Indian girl-group "The Models", and Sonu Nigam, as well as continuing his collaboration with Alisha Chinoy on her Dil Ki Rani album. Into the new millennium, he produced two hit albums with Sansara, Yeh Dil Sun Raha Hai and Habib.
