It's a song from the Tony Award-winning British musical Oliver! and the 1968 film Oliver! based on the novel Oliver Twist by Charles Dickens. The musical was written by Lionel Bart and was first staged in London's West End in 1960.
In the 1968 musical film version of Oliver!, "Where is Love?" was performed onscreen by Mark Lester, whose singing voice was reportedly dubbed by Kathe Green (the daughter of the film's conductor and musical arranger, Johnny Green), though Lester was actually given credit on the soundtrack album.
Where is love? Does it fall from skies above? Is it underneath the willow tree That I've been dreaming of?
Where is she? Who I close my eyes to see? Will I ever know the sweet hello That's meant for only me?
Who can say where she may hide? Must I travel far and wide? 'Til I am beside the someone who I can mean something to ... Where...? Where is love?
