One of the films that starred Amitabh Bachchan and Rishi Kapoor was Ajooba, which released in 1991.
The film was
directed by Shashi Kapoor (who was a frequent co-star of the former, and the
younger paternal uncle of the latter).
The only song from
the film in my collection was Arre Tajjub Hai.
But there was no tajjub
(surprise) in the fact that Sudesh Bhosle sang Bachchan’s portion.
And Rishi
lip-synched to the voice of Mohammed Aziz.
The track, which
was written by Anand Bakshi, was composed by Laxmikant Shantaram Kudalkar and
Pyarelal Ramprasad Sharma.
