(originally by The Who)

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!
Don't you know I'll be your substitute
Whenever you need me, 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
'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, ooh!
Don't you know I'll be your substitute
Whenever you need me, ooh!
Each day by your window
You sit and sigh hoping to see her face
Aw, 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, ooh!
Don't you know I'll be your substitute
Whenever you need me, ooh!
Don't you know I'll be your substitute
Whenever you want me, ooh!
Don't you know I'll be your substitute
Whenever you need me, ooh!
Don't you know I'll be your substitute
Whenever you want me, ooh!
Don't you know I'll be your substitute
Whenever you need me, ooh!
