What's the reason, Daddy??

[DuffyMoon]

Trying to find a the title and lyrics of a sentimental song about a blind boy that my mum liked to sing to us as kids...

What's the reason, Daddy
That I can't see like you?
I've often wondered what you're like,
Though I know you're kind and true.

i found even a sample for this song, but i don't know this song.
Here's the sample, maybe someone else knows: http://www.meades.org/trevor/whats_the_reason_daddy.mp3

I think, the title is What's the reason Daddy, as i see it on this CD: http://www.tagtuner.com/music/albums.../album-v21193d

That's definitely the one.
Can't seem to find lyrics, though.
