Lyrics:

Sam, you've been waitin' much too long now
It looks like she's not comin' home
Sam, you've been loyal, true and faithful
All this time with bein' alone

If I could get that same dedication
I'd give you everything in creation
If she doesn't come back
(If she doesn't come back)

I'll be your substitute
Wherever you want me
Don't you know I'll be your substitute
Whenever you need me

Sam, everyday you waited for her
I've been waitin' here for you
Sam, all this time I've been lonely
I know what you've been going through

I'll wait until my chances occur
'Cause you can't keep relyin' on her
If she doesn't come back
(If she doesn't come back)

I'll be your substitute
Wherever you want me
Don't you know I'll be your substitute
Whenever you need me

Each day by your window
You sit inside, hopin' to see her face
Oh, you might as well forget about her
And find someone to take her place
(If she doesn't come back)

I'll be your substitute
Whenever you want me
Don't you know I'll be your substitute
Whenever you need me

Don't you know I'll be your substitute
Whenever you want me
Don't you know I'll be your substitute
Whenever you need me

Don't you know I'll be your substitute
Whenever you want me
Don't you know I'll be your substitute
Whenever you need me

Don't you know I'll be your substitute
Whenever you want me
Don't you know I'll be your substitute
Whenever you need me
