Cover art for Mary-Lou lyrics by Sonata Arctica

appears on wht?? n wht???

obviously, song about a girl running away with her "love of her life" but he betrays her, all he did was get sex, get her pregnant n get another girl...

Mary-Lou... marry you... he won't marry you, says the song... like in "Shamandalie" Sham and a lie...

"life isnt gray"? i dont get that...

also he says that she wants to go to her parents again "Need to come home again" "Despite all the papers been signed mama take me back be so kind"

altho maybe he did marry her, "all the papers been signed" as in the marriage.... n since she's married, she's not supposed to go home...

you forgot the most important verse

Mamas do your children still sleep In the safe of their cradles so sweet? Story I told you I have foreseen Your little angel ain't always so clean Days to come aren't easy to see You can change 'em but it isn't free I see that you don't believe Ho... but you will see.

this verse implies that whatever happened in the song has NOT happened yet, and the 'narrator' is telling Mary Lou what will happen to her

I think maybe the papers referred to in the song may be emancipation papers. Either theory works, in my opinion, considering that Mary-Lou seems to be a young woman.
