At one point in the book Winston was in the room above Mr.Charrington's shop while he overheard a prole woman singing while hanging her laundry out to dry. The song was,
"It was only an 'opeless fancy,
It passed like an Ipril dye,
But a look an' a word an' the dream they stirred
They 'ave stolen my 'eart awye!"
Is this song of importance and who is she talking about when she sings, "They 'ave stolen my 'eart awye!"?
