Lyrics:

Sam
You've been waiting much too long
Now it looks like she's not coming home
Sam
You've been loyal
True and faithful
All this time with being 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
Whenever you want me

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

Sam
Every day you waited for her
I've been waiting here for you
Sam
All this time I've been lonely
I know what you've been going through
I'll wait until an't chances will come
'Cause you can't keep relying on her
If she doesn't come back

(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

Each day by your window you sit and sigh hoping to see her face
Ay
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
