The song in CID (1956) directed by Guru Dutt was copied from this song below:
While “Oh My Darling Clementine” has a sad tone and sad lyrics like “you are lost forever and gone”; the CID song gives one a hope!
What is the difference in these two songs? Is it the singer? Is it the Music Director?
It’s the lyrics. Especially the line “Ye Hai Bombay Meri Jaan” by Sahir Ludhianvi is what makes the song. The song has hope and is a joyful song, not because of music but because of lyrics!
