"I Want Some More" b/w "Pay Me Later"

According to Russo's Collector's Guide, fifty years ago to-day (20 April 1973) Colin Blunstone's "I Want Some More" (edit) b/w "Pay Me Later" (Dut. Epic EPC 1513) was released (I'm assuming the "Dut." abbreviation means it was a Dutch release).  The U.S. and Canada release (Epic 5-10981) was on 23 April.
