^Due to a two-week break in publication for the 1974/1975 Christmas and New Year period, the week of January 4 is inferred.
^No issue was published for March 8, so this week is inferred.
^The issue containing this chart was intended for publication in October 11, but was delayed to October 13, so the date.
^RPM's publication schedule indicates a hiatus throughout November 1975 up to December 6, when a combined issue (volumes 24, issues 10, 11 and 12) was published for the week of December 13. Since no "last week" positions are provided in the chart for that issue, the charting process was restarted.
