Lyrics:

How long is the river?
How deep is the sea?
How long is forever?
That's how long you'll love me

My heart is beating fast
I found true love at last
I'm so optimistic
I know this new love will last

How high is the mountain?
How far out of space?
How long could I hold you
in a lover's embrace?

Until the end of time
A love that's so divine
I'm so optimistic about
this new love of mine
