There's a number of songs that aren't considered "soul music" that have the title & lyrics "Heart & Soul".

The song I associate with that title is this Jan & Dean song:

HEART & SOUL
{Jan & Dean}

Bom ba bom, bom ba dip, da dip, dip da
da, da, da, dun, dun, da dingity ding, da ding.
Bom ba bom, bom ba dip, da dip, dip da
da, da, da, dun, dun, da dingity dong, da dong.

Heart and soul, I fell in love with you,
Heart and soul, the way a fool would do,
Madly...
Because you held me tight,
And stole a kiss in the ni-ight...

Heart and soul, I begged to be adored(ooooh ooh),
Lost control, and tumbled overboard(ooooh oooh ooh),
Gladly...
That magic night we kissed,
There in the moon mist.

Oh! but your lips were thrilling, much too thrilling,
Never before were mine so strangely willing.

Uh huh, but now I see, what one embrace can do,
Look at me, it's got me loving you,
Madly...
That little kiss you stole,
Held all my heart and soul.

Bom ba bom, bom ba dip, da dip,dip da
da, da, da, dun, dun, da ding, da ding, da dong.
Bom ba bom, bom ba dip,da dip,dip da
bom, ba ba bom, bom, dip, da dip, da dip.

(Instrumental)

Oh! but your lips were thrilling, much too thrilling,
Never before were mine so strangely willing.

Yeah, but now I see, what one embrace can do,
Look at me, it's got me loving you,
Madly...
That little kiss you stole,
Held all my heart and soul.
