Lyric discussion by greatrayray 

This is such a sad song, because it's about Avey and Kria Brekkan's divorce.

Think about it:

The whole song is a guy watching his sleeping former lover, getting lost in her curls and dreaming of a simpler time when they were still together.

Back when we were green: means the opposite of blue (sad), he's looking back on better times.

She has clearly gotten over him, evinced from the line "I know we have changed But I still grin 'cause I can't wait to see you".

That's why they've never played it live, and attributed that to something like a "missing sampler"

"Green" actually often means new. Not good, or even still together.

I think that line is about how nervous he was with her at the beginning of their relationship. And the whole song is about how he's still completely enthralled even after all this time.
