Have the lyrics, need the artist. Can you help?

Scavenger hunt! Can anyone help?

I have lyrics, and I'm looking for the artists. Could be 1980s, but possibly earlier.

1.

There's a man I know,
who's got a heart so full of joy,
it can make you fly.
There's a man I know,
who's got a soul so full of pain,
it can make you cry...

2.

The joke's on me,
I thought that I knew it all,
but one look at you and
I feel myself falling.
I'm finally melting, it's happening fast,
you've broken the ice and now,
you'll be the last
for a long, long time,
a long, long time...

3.

Tropical paradise,
but the beauty escapes me.
Everything should be so right
for falling in love,
two hearts belong
where one heart remains,
so unhappy,
nothing else matters to me,
no, nothing at all...

You've got me. I have been searching for three days and found nothing. If you can remember how the tune went, or some other words, feel free to come back and post. I'm giving up.

Sorry.

Thank you for your diligence. I'm afraid the lyrics above are all I have to go on. They are provided as clues in a scavenger hunt - I never heard the music.
