Disco song- "100 percent" probably an easy one

*Now with clip- see below, I suspect its an easy one.

My guess is late 70s, an uptempo disco track. With a female vocalist and memorable piano riff. Lyrics in the bit I heard kept repeating something like 'I'll be rooting for you.. one hundred percent"

I've googled it but all I get are links to Double Exposure or Miquel Brown which aren't right

Here's a very crude interpretation of the piano riff, if it helps :p

Reminds me of Patrice Rushen - Haven't You Heard
