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 (ooh-ooh)
Don't you know I'll be your substitute
Whenever you need me (ooh-ooh)

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 my chances occur
'Cos you can't keep alying on her
If she doesn't come back (if she doesn't come back)

I'll be your substitute
Whenever you want me (ooh-ohh)
Don't you know I'll be your substitute
Whenever you need me (ooh-ooh)

Each day by your window you sit and sigh hoping 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
When ever you want me (ooh-ooh)
Don't you know I'll be your substitute
When ever you need me (ooh-ooh)

Don't you know I'll be your substitute
When ever you want me (ooh-ooh)
Don't you know I'll be your substitute
When ever you need me (ooh-ooh)

Don't you know I'll be your substitute
When ever you want me (ooh-ooh)
Don't you know I'll be your substitute
When ever you need me (ooh-ooh)
