Not sure you are wrong there, apparently chrissie wrote it , here’s what songfacts says
This was written by Chrissie Hynde of The Pretenders, as "like all the other London punks, I wanted to do reggae." It was included on The Pretenders 1980 self-titled debut album but when the singer heard Jones' version she conceded, "That's how it's supposed to be done."
Jamaican musical legends Sly Dunbar & Robbie Shakespeare supplied the backing to this track.
