* NOTE: Although the official Irish charts recommenced on 5 October (week ending 4 October), the Irish charts website still lists the Hot Press chart for 26 September – 9 October fortnight. This give the No.1 to be "Feels Like I'm in Love" by Kelly Marie, taking away the first two weeks of The Police's "Don't Stand So Close to Me". In reality, viewed from the variation on publication dates, this effectively gives Kelly Marie a two-day No.1 (26-27 September).
