The tune of the mukhda of this song was inspired by Jose Feliciano's "Listen To The Falling Rain". This song was previously used in a medley sung by Usha Iyer in "Bombay To Goa" (1972). The tune of "Rain" was used in other Hindi film songs as well - Satyam's "Mere Dil Jhoom Jhoom Tu Gaaye Ja" ("Rani Aur Jaani", 1973) and Anu Malik's "Sun Sun Sun Barsaat Ki Dhun" ("Sir", 1993). R.D. Burman also adapted the flute solo in "Rain" for the song "Jaane Jaan Dhoondhta Phir Raha" ("Jawani Diwani", 1972).[1][2][3][4][5]
