साजन आ जा

'Sajan Aa Ja' (documented in full as 'Sajan Aa Ja, Rajan Aa Ja, Khelein Dil Ke Khel') is a documented duet of the 1944 Lahore film Bhai, sung by Zeenat Begum with music director Ghulam Haider himself — an unusual instance of the composer lending his own voice. Set to a Shatir Ghaznavi lyric of romantic invitation, it is the film's playful courtship number and survives across the principal gramophone discographies of Bhai.

Ghulam Haider gives the duet a flirtatious, mid-tempo lilt — dholak and tabla keeping a light, danceable pulse while the two voices trade the invitation back and forth. That the composer sings the male part himself shades the arrangement toward an easy, conversational intimacy rather than a staged grand romance, in the call-and-response idiom the era favoured for its lighter love duets.
