Cover art for Punky Reggae Party lyrics by Bob Marley and the Wailers

Your wish is my command :)

Yeah, the song's about a party, but not just any old party. Marley is celebrating the solidarity between Jamaica's dub and reggae scene with the UK punk and new wave scene of the late 70s. They didn't have to be related by sound just to share a worldview, but sometimes they did anyway. Check out a group like The Slits, or The Clash's cover of Junior Murvin's "Police and Thieves".

Basically, he's saying that since we're all on the same page, why not dance the night away together?

"Rejected by society Mistreated with impunity Protected by my dignity I search for reality"

To me, any one of the punk outfits of the time could have said something like that. You don't have to be black to know (and be appalled) that anyone can be treated like niggers.
