The SS single that has "Don't stop" on the other side was the WB reissue on their "back to back hits" series when they would reissue old singles for the "oldies but goodies" sections of record stores (when they used to sell vinyl, let alone vinyl singles!). The original pressings of the GYOW single had SS on the B-side. I think on the WB "back to back hits" series version of the GYOW single, "Dreams" was on the B-side but I'm not sure as I don't collect singles unless I can't get the songs on them elsewhere but I think that was it and I think the original "palm tree" pressings of the "Don't stop" single had "Never going back again" on the B-side (in the US anyways). I hope that was of some help.
