song = '''
Can't believe its over
That you're leaving
Weren't we meant to be?
Should've sensed the danger
Read the warnings
Right there in front of me
Just stop
Lets start it over
Couldn't I get one more try?
All:
Maybe tomorrow you'll say that you're mine
You'll realize, I could change
I'm gonna show you I'm in it for life
I'll get you back someday
Maybe tomorrow
Shane:
I forgot to be there
I was selfish
I can see that now
Mark:
I should've got to known you
Should've held you
When your tears fell down
Just stop
Don't make me beg you
Tell me that you'll stay the night
All:
Maybe tomorrow you'll say that you're mine
You'll realize, I could change
I'm gonna show you I'm in it for life
I'll get you back someday
I will find a way
Nicky:
Wait a minute
Just hear me out
This time I promise, I'll put you first
Shane:
Turn around now
Your heart can't let you walk away
I'll do what it takes
All:
Maybe tomorrow you'll say that you're mine
You'll realize (realize), I could change (I can change)
I'm gonna show you I'm in it for life
I'll get you back someday
Maybe tomorrow
Kian:
There's so much I wanna say now
I just wanna make a life with you (don't walk away)
There's so much I wanna do now
I just wanna make love to you
Shane:
Maybe tomorrow
