Well James was in a school musical in 2006 called Mulan. He played Mulan’s father and was quite taken by the song “True to Your Heart” sung by Stevie.

When he learned that Stevie was blind, James felt that it would be great to have him sing at the concert partly because of his singing and also because Stevie like James would know what it meant not to be able to see. (Click "read more" to view the lyrics to the song “True to Your Heart”.)

True to Your Heart (Single)

Vocals: 98° and Stevie Wonder, Music: Matthew Wilder, Lyrics: David Zippel

Baby, I knew at once that you were meant for me
Deep in my soul I know that I'm your destiny
Though you're unsure why fight the tide
Don't think so much, let your heart decide

Baby, I see your future and it's tied to mine
I look in your eyes and see you searching for a sign
But you'll never fall till you let go
Don't be so scared of what you don't know

(Chorus:)
True to your heart
You must be true to your heart
That's when the heavens will part
And baby, shower you with my love
Open your eyes
Your heart can tell you no lies
And when you're true to your heart
I know it's gonna lead you straight to me

Someone ya know is on your side, can set you free
I can do that for you if you believe in my
Why second-guess what feels so right
Just trust your heart
And you'll see the light

Your heart knows what's good for you
Let your heart show you the way
It'll see you through

Girl, my heart is driving me to where you are
You can take both hands off the wheel and still get far
Be swept away
Enjoy the ride
You won't get lost
With your heart to guide you

When things are gettin' crazy
And you don't know where to start
Keep on believin', baby
Just be true to your heart
When all the world around yu
It seems to fall apart
Keep on believin', baby
Just be true to your heart
