The single was certified gold by the Recording Industry Association of America on 14 December 1970 for sales of over 1 million copies. It reached number 1 on the US "Billboard" Hot 100 on 26 December, remaining on top for four weeks, three of which coincided with "All Things Must Pass"s seven-week run atop the "Billboard" albums chart. While "Billboard" recognised both sides of the single in the US, only "Isn't It a Pity" was listed when the record topped Canada's "RPM" 100 chart.
