Letra de Scratch My Back - Slade

Whoa-a-oh oh oh - how long can you go?
Oh can you go a dozen times?
How long can you smile or can you smile a dozen smiles?
'Cos every way holds something that's nice
Try it once and then you'll try it twice

Oh mercy mercy, oh lawdy lawdy
I'll scratch your back if you'll just scratch mine
'Cos when I'm outta sight then I'm out of mind
Oh mercy mercy, do it over and over again, oh lawdy lawdy

How long will it last? it's getting harder off the cuff
How long does it take? there must be someone with enough
'Cos every time holds something that's better ?
Go on, get on up and forget the letter
Mercy mercy, oh lawdy lawdy -
'Ll scratch your back if you'll just scratch mine

'Cos when I'm outta sight then I'm out of mind
Oh mercy mercy, do it over and over again, oh lawdy lawdy
Oh mercy mercy mercy - scratch my back
Just a little bit higher

How much do you need? what does it take to get you off?
No-one's ever made it? are you tryin' to make me laugh?
'Cos until now you have tried all the rest -
So now's the time you got to try out the best

Oh mercy mercy, oh lawdy lawdy lawdy
I'll scratch your back if you'll just scratch mine
'Cos when I'm outta sight then I'm out of Mind
Oh mercy mercy, do it over and over and over and over again,
Oh lawdy lawdy
