any1 help me on this please,

it's a tune from the early 90's late 80's maybe
the lyrics go like this

"the skys the limit you know, if you keep on just keep on pressin on"
"gotta keep on pressin on gotta keep keep keep on pressin on"

when it breaks down in the middle and says
"gotta keep on pressin on" and keeps repeating
it slows down and distorts i.e has some sort of effect over it.

also it is none of the below,
Brenda - Sky
Nitelite Cityrama - Runnin' So Hard
Shades of Rhythm - Exstacy

they all have the the same sample of the lyrics in them
but are not the tune i am after,
any help is appreciated
