Mohammed Rafi's “Khanke To Khanke Kyon” is a lively Hindi film duet from *Vallah Kya Baat Hai*, the 1962 comedy starring Shammi Kapoor and Beena Rai. Rafi shares the performance with Asha Bhosle, whose lighter vocal tone plays against his full, resonant delivery. The song turns a short, percussive phrase into a rhythmic hook, giving the number a playful character that fits the film's lighthearted tone.

Roshan composed the music for the film, bringing his melodic sensibility to a recording shaped around vocal interplay and a buoyant orchestral backing. The track is part of the classic Hindi playback tradition, in which the singer's voice represents an on-screen character and the song becomes a compact scene in its own right. The combination of Rafi and Bhosle was especially effective for such material: their contrasting voices made the duet feel conversational without losing its musical polish.

A reliable standalone chart position is not available for the film song, but it remains part of the soundtrack's continuing circulation through old-film collections and digital services. Its most useful context is the pairing of two major playback singers with Roshan's score for a popular early-1960s comedy. “Khanke To Khanke Kyon” offers an upbeat counterpoint to the more solemn songs often associated with Rafi's repertoire, demonstrating how easily he could move into a teasing, playful performance.
