Finally found the lyrics for the piano demo of Tim McGraw and it's really beautiful. A lot of lyrics was changed (I think) from the original version of the song.

Lyrics:

You said the way my blue eyes shined

put those Georgia stars to shame that night

I said “that’s a lie.”

Just a boy in a pick up truck

That had a funny way of getting stuck

On back roads at night

And I was right there beside you

All summer long

And then the time we woke up to find that summer’d gone

But when you think Tim McGraw

I hope you think my favorite song

The one we danced to all night long

The moon like a spotlight on the lake

When you think happiness

I hope you think that little black dress

The one you said you always liked best

Next to my old faded pair of jeans

When you think Tim McGraw,

I hope you think me.

September saw a month of tears

And thankin God that you weren’t here

To see me like that

But in a box beneath my bed

is a letter that you never read

From three summers back

It’s hard not to find it all a little bittersweet

And looking back on all of that

It was love to me

When you think Tim McGraw

I hope you think my favorite song

The one we danced to all night long

The moon like a spotlight on the lake

When you think happiness

I hope you think that little black dress

The one you said you always liked best

Next to my old faded pair of jeans

When you think Tim McGraw,

I hope you think me

And I’ve been back a couple times since then…

I’ve been back a couple times since then

And I didn’t look you up,

Cuz some trains you can’t catch again

You gotta leave it as it was

When you think Tim McGraw

I hope you think my favorite song

The one we danced to all night long

The moon like a spotlight on the lake

When you think happiness

I hope you think my little black dress

The one you said you always liked best

Next to my old faded pair of jeans

When you think Tim McGraw,

When you think Tim McGraw

I hope you think of me

He said the way my blue eyes shined

Put those Georgia stars to shame that night

I said that’s a lie.
