Side B is Jennifer Lara (sometimes credited as "Positive Vibes") performing "Play That Song for Me" ohn the "Fattie Fattie" rhythm

"Kiwana followed her passion for music and began recording and preforming background music for various artists and in 1984 formed "Positive Vibes" with reggae performer Marcia Hall. The group enjoyed moderate success but their sites were set on making it in the fickle music business. In 1985, Kiwana was introduced to Coxsone's Studio One label and recorded a song titled "Play That Song." An excerpt from Kiwana's facebook page.

NO, that's not Jennifer Lara at all, but a reggae band called Positive Vibes from New York. They had another outing around the same time on here: http://www.discogs.com/Positive-Vibes-Give-Me-The-Right/release/2919852 on another Bronx based labelSame singer, same unmistakeable sibilant lisp on her voice, probably her name is Rose Marie James - don't know further details though. But not Jennifer, that's a common misbelief.Some copies seem to come with this label: http://www.reggaerecord.com/rc/shared_img/item_2/101381/101381_02_360.jpgYep: R.M. James as I suspected.
