The B-side is not a Version of "Police & Thieves", as the run-out groove indicates, it's the Version of "Beat Down Babylon" by Junior Byles & The Upsetters.
NOTE: The copyright notice for Sunset Records and its publishing company, Cari-Blue, were stamped in the label as a default since Sunset was their distributor and made it practice to have that information on all product which it had involvement in.
"Police And Thieves" was originally released in 1976. This reissue by Sunset was released in 1984 and it was also one of the few, rare instances of Sunset Records distributing Lee Perry material.
