Shailendra was not delivering a specific song to S D Burman for this film. One day he was called by S D Burman to his house,who then ordered his son R D Burman to follow Shailendra wherever he goes,and not to come back home without getting the song from him. Both went to the quiet Juhu beach and walked for a while late in the night, a pleasant full moon night with clear sky. Within no time Shailendra came up with the lyrics of "Khoya Khoya Chand, Khula Aasman",and RD also took a sigh of relief.
