"Change The World"

If I could reach the stars
Pull one down for you,
Shine it on my heart
So you could see the truth:

That this love inside
Is everything it seems.
But for now I find
It's only in my dreams.

<em>And</em> I can change the world,
I will be the sunlight in your universe.
You would think my love was really something good,
Baby if I could change the world.

If I could be king,
Even for a day,
I'd take you as my queen;
I'd have it no other way.

And our love would rule
This kingdom we had made.
'til then I'd be a fool,
Wishing for the day...

<em>That</em> I can change the world,
I would be the sunlight in your universe.
You would think my love was really something good,
Baby if I could change the world.
Baby if I could change the world.

I could change the world,
I would be the sunlight in your universe.
You would think my love was really something good,
Baby if I could change the world.
Baby if I could change the world.
Baby if I could change the world.

<em>And</em> I can change the world,

not 

<em>That</em> I can change the world,

<em>I think the first 'if'-clause should be 'If I could change the world'.</em>

<em>Why is it actually 'can'? Is there any reason?</em>

The obvious answer is that it's a mixed conditional. We're not limited to the simple conditional patterns, expecially if they don't fit the context.

The less-obvious answer is that you have the wrong lyrics. These lyrics match the song (yes, I checked):  http://www.azlyrics.com/lyrics/ericclapton/changetheworld.html

Chorus 1:

<em>And I can change the world,</em>
<em>I will be the sunlight in your universe.</em> (No problem here - it's not a conditional)

Chorus 2:

<em>(Wishing for the day...)</em>

<em>That I can change the world,</em>
<em>I would be the sunlight in your universe.</em> (again, not a conditional)

Chorus 3:

<em>I could change the world,</em>
<em>I would be the sunlight in your universe.</em> (and once more... not a conditional)

No rules broken here, says Mr Clapton. ;)

And our love would rule
This kingdom we had made.
'til then I'd be a fool,
Wishing for the day...

That I can change the world,
I would be the sunlight in your universe.
You would think my love was really something good,
Baby if I could change the world.
Baby if I could change the world.

The last one is 'That'. But to be honest, I cannot hear the differece. Its really hard to hear for non-English speaker...

Thank you to reply Aegis

Peachey,

Thanks for your comments.

Yes,,,the lyrics should be <em>'That</em> I can change the world', I was looking the lyrics in a Chinese website...

You and Mr Clapton are right.
