It's one of the few you can get in both colours around that time as the label colour was changing. The yellow Epics all came in plain sleeves though, not yellow ones. "Play that funky music" , "Dancing Queen" and "Doina de jale" all appeared yellow at first.Comment by ZebedyZak:
I listened to "Howzat" on YouTube today after someone mentioned it in a pub the other day. I don't remember seeing it with the old-style yellow label. I never bought it myself, but I saw many copies in shops at the time. They all had the light orange label shown at the right side of this page. Is the yellow label pressing rare? It charted in the UK a month after its release, so I'm guessing the yellow labels were from the initial batch.
