What Sound

What is that sound, ringing in my ears The strangest sound, I've heard for years and years The sound of two hearts, beating side by side The sound of one love, that neither one can hide The sound that makes the world go 'round The sound that makes the world go 'round What is that sound, running 'round my head Funny I thought, that part was long since dead But now there's new life, coursing through my veins Because there's someone, who'll make it beat again The sound that makes the world go 'round The sound that makes the world go 'round The sound that makes the world go 'round The sound that makes the world go 'round What is that sound, ringing in my ears The strangest sound, I've heard for years and years The sound of two hearts, beating side by side The sound of one love, that neither one can hide
