Deep and Wide?

We've all sang the song "Deep and Wide," but Abby and I don't understand what it means.

We started singing it to each other and we were convinced that we were forgetting lines b/c all we could remember was:

Deep and wide
Deep and wide
There's a fountain flowing deep and wide
Deep and wide
Deep and wide
There's a fountain flowing deep and wide

Well that turns out to be all of the song. Sometimes after singing it normally once, the second time people sing it:

Hmm and wide
Hmm and wide
There's a fountain flowing deep and wide
Hmm and wide
Hmm and wide
There's a fountain flowing Hmm and wide

Then the next go round "wide" is Hmm'ed out. I don't get it. If you do please enlighten me. I'm sure it's referring to God's love, mercy, grace...anything fits, but when I sang it as a kid I had no clue. It was probably explained, but of course that part didn't stick. I tried to find a scriptural reference for it, but I couldn't find anything. I've googled it, but I cannot find its history. Speaking of history of a song, the movie Amazing Grace is awesome. I'm watching it right now. If you haven't seen it, rent it and check it out.

Back to "Deep and Wide," I did find on google more lyrics to the song. I thought they were hilarious. I sang them all out loud to Abby w/ a beautiful country accent. She didn't think it was as funny; she turned up her music to drown me out. Here is the remix of "Deep and Wide":

Plunge Right in,

Cleanse your sin,

there's a fountain flowing deep and wide

Plunge Right in,

Cleanse your sin,

there's a fountain flowing deep and wide!

Broad and tall,

broad and tall,

There's a cross on Calvary broad and tall.

Broad and tall,

broad and tall,

There's a cross on Calvary broad and tall!

Kneeling down,

kneeling down,

There's a poor lost sinner kneeling down.

Kneeling down,

kneeling down

There's a poor lost sinner kneeling down!

Saved by grace,

saved by grace,

There's a poor lost sinner saved by grace.

Saved by grace,

saved by grace,

There's a poor lost sinner saved by grace!
