Maybe two...

"I remember what you wore on the first day
You came into my life and I thought
"Hey, you know, this could be something"
'Cause everything you do and words you say
You know that it all takes my breath away
And now I'm left with nothing

'Cause maybe it's true
That I can't live without you
Maybe two is better than one
There's so much time
To figure out the rest of my life
And you thought that it got me coming undone
And I'm thinking two is better than one

[...]
'Cause when I close my eyes and drift away
I think of you and everything's okay
I'm finally now believing"

"We were a thousand miles from comfort
We have travelled land and sea
But as long as you are with me
There's no place I'd rather be
I would wait forever
Exalted in the scene
As long as you I'm with you
My heart continues to beat

[...]
We're different and the same
Gave you another name
Switch up the batteries

If you gave me a chance I would take it
It's a shot in the dark, but I'll make it
Know with all of your heart, you can't shame me
When I'm with you, there's no place I'd rather be"
