Looking for a Bob Marley song. Please help :-)

Hi, I'm looking for a Bob Marley song with the same bassline as the first 20 seconds of the 12-inch of Walking on sunshine from Katrina & the waves:

Does anybody know it? Thanks :-)

I mark this as SOLVED:

It's Jimmy Cliff - Rock children OR
Bob Marley - Memphis OR
Bob Marley - Mr. Brown

I don't remember any more. These songs sound alike, so it's one of these. SOLVED.
