[Verse 1]
I'd be in the hall of fame
The mere mentioning of your name
If they knew I love you the way that I feel
And kissing couldn't be a shame, when you love someone
And falling in love there's no blame when it's all said and done

[Pre-Chorus]
And I never knew, about this thing, yeah
'Cause there were no clues, oh, what a shame

[Chorus]
Oh, when you stop, and start falling in love
It changes your whole world, turns you upside down
I never knew (Oh, I never knew) about real love (Real love)
It changes your whole world (Turns your world upside down, mmm, mmm)

[Verse 2]
I must admit I stand accused of falling in love
Long before you said "hello," and I said "I do" (I do, I do)
It was all new to me, an unfamiliar world
A beauty unknown to man and a cure for the blues

[Pre-Chorus]
And I never knew about this thing, yeah
And oh-oh, there were no clues, oh, oh, what a shame
[Chorus]
Oh, when you stop (Oh, oh, when you stop), and start falling in love
(Start falling in love)
It changes your whole world (Turns you upside down)
I never knew (Say I never knew) about real love
(Can't you see I never knew about real love?)
It changes your whole world
(Yes, it does; oh, yes, it does; oh oh oh oh oh yeah)

[Outro]
It changed my whole world, whoa-oh-oh-whoa, yeah (Whoa, yeah)
Should've known what love is
Now I know what love is, yeah, yeah, yeah
Love, now I know, baby, baby, yeah, yeah
Oh-oh
