Best mates as well as lovers

Anyone name a song re the importance of being best mates as well as lovers?

The Moldy Peaches had this song called Anyone Else But You. It sorta touches the subject, here's the lyrics:

You're a part time lover and a full time friend
The monkey on your back is the latest trend
I don't see what anyone can see, in anyone else
But you

I kiss you on the brain in the shadow of a train
I kiss you all starry eyed, my body's swinging from side to side
I don't see what anyone can see, in anyone else
But you

Here is the church and here is the steeple
We sure are cute for two ugly people
I don't see what anyone can see, in anyone else
But you

The pebbles forgive me, the trees forgive me
So why can't, you forgive me?
I don't see what anyone can see, in anyone else
But you

I will find my nitch in your car
With my mp3 DVD rumple-packed guitar
I don't see what anyone can see, in anyone else
But you

Du du du du du du dudu
Du du du du du du dudu
Du du du du du du dudu du

Up up down down left right left right B A start
Just because we use cheats doesn't mean we're not smart
I don't see what anyone can see, in anyone else
But you

You are always trying to keep it real
I'm in love with how you feel
I don't see what anyone can see, in anyone else
But you

We both have shiny happy fits of rage
You want more fans, I want more stage
I don't see what anyone can see, in anyone else
But you

Don Quixote was a steel driving man
My name is Adam I'm your biggest fan
I don't see what anyone can see, in anyone else
But you

Squinched up your face and did a dance
You shook a little turd out of the bottom of your pants
I don't see what anyone can see, in anyone else
But you

Du du du du du du dudu
Du du du du du du dudu
Du du du du du du dudu du
But you

Thanks for that - the last verse will really touche his heart lol!

Try "You've Got A Friend" by Carole King (covered by James Taylor)

How about "You're My Best Friend" by Queen? It's rather simplistic, but it doesn't need to be more complex, it tells a good story on its own.

Try My Best Friend by Tim Mcgraw
here are the lyrics for u i think it might be just the thing

I've never had no one
I could count on
I've been let down so many times
I was tired of heutin
So tired of searchin
Till u walked into my life
It was a feelin
I'd never known
And for the first time
I didn't feel alone

Chorus:
You're more than a lover
There could never be another
To make me feel the way u do
Oh we just get closer
I fall in love all over
Everytime i look at u
I don't know where i'd be
Without u here with me
Life with u makes perfect sense
You're my best friend
You're my best friend Oh yeah

Youstand by me
And you believe in me
Like nobody ever has
When my world goes crazy
You're right there to save me
You make me see how much i have
And i still tremble
When we touch
And oh the look in your eyes
When we make love

Chorus:
You're more than a lover
There could never be another
To make me feel the way you do
Oh we just get closer
I fall in love all over
Everytime i look at you
I don't know where i'd be
Without you here with me
Life with you makes perfect sense
You're my best friend
You're my best friend

You're more than a lover
There could never be another
To make me feel the way you do
Oh we just get closer
I fall in love all over
Everytime i look at you
I don't know whre i'd be
Without you here with me
Life with you makes perfect sense
You're my best friend
You're my best friend(my best friend)
You're my best friend(my best friend)
