OLIVIA NEWTON JOHN/ELO Xanadu (Legendary original 1980 US promotional only 10" picture disc. It is believed that only 31 of these were manufactured by MCA before the idea was scrapped. It has since become the Holy Grail to ONJ, ELO and picture disc collectors. It plays the title track both sides - a song so good you should play it twice - this is likely to be the only chance you have to purchase one of these!)
