He was so proud of his little girl.
It was her very first day of school.
He walked with her to school that day,
And she held his hand all the way.
They walked together quiet and sad,
A little girl and her loving dad.
Into the school her father led,
But he almost cried when she said,
"Daddy, Daddy, please don't go.
Don't leave me here all alone.
I'll miss you if you go away,
And I might need you; can't you stay?"
"Little Daughter, please don't cry.
You'll be okay, so dry your eyes.
You have our memories in your heart.
We're together though we're apart."

He sat up front on her wedding day
And cried as his daughter walked away.
Later that night he watched her dance.
He sat there waiting for his chance.
The band started to play their song.
Father and daughter danced along.
She looked at him and saw a tear
Then leaned and whispered in his ear,
"Daddy, Daddy, I have to go.
I hate to leave you all alone.
I'll miss you when I go away,
But if you need me then I'll stay."
"Little Daughter, I'll be just fine.
I'll love you always; you are mine.
I have our memories in my heart.
We're together though we're apart."

She came in his room and kissed his head
Then sat next to his hospital bed.
He took her hand and held it tight
And wished he had the strength to fight.
They sat together, quiet and sad,
A daughter and her dying dad.
He saw the tears she tried to hide.
She looked at him and then she cried.
"Daddy, Daddy, please don't go.
Don't leave me here all alone.
I'll miss you when you go away.
I still need you; you have to stay."
"Little Daughter, I love you so.
I want to stay but have to go.
I'll always be here in your heart.
We're together though we're apart."

The club isn't the best place to find a lover 
So the bar is where I go 
Me and my friends at the table doing shots 
Drinking faster and then we talk slow 
Come over and start up a conversation with just me 
And trust me I'll give it a chance now 
Take my hand, stop! Put Van The Man on the jukebox 
And then we start to dance, and now I'm singing like 


Girl, you know I want your love 
Your love was handmade for somebody like me 
Come on now, follow my lead 
I may be crazy, don't mind me, say 
Boy, let's not talk too much 
Grab on my waist and put that body on me 
Come on now, follow my lead 
Come—come on now, follow my lead 


I'm in love with the shape of you 
We push and pull like a magnet do 
Although my heart is falling too 
I'm in love with your body 
And last night you were in my room 
And now my bedsheets smell like you 
Every day discovering something brand new 
I'm in love with your body 
Oh—i—oh—i—oh—i—oh—i 
I'm in love with your body 
Oh—i—oh—i—oh—i—oh—i

Every day discovering something brand new 
I'm in love with the shape of you 


One week in we let the story begin 
We're going out on our first date 
But you and me are thrifty so go all you can eat 
Fill up your bag and I fill up a plate 
We talk for hours and hours about the sweet and the sour 
And how your family is doin' okay 
And leave and get in a taxi, we kiss in the backseat 
Tell the driver make the radio play, and I'm singing like 

 
Girl, you know I want your love 
Your love was handmade for somebody like me 
Come on now, follow my lead 
I may be crazy, don't mind me, say
