"One Perfect Day" is a song written and sung by Roger Hart-Wells and performed by the Australian band Little Heroes.
It was released in March 1982 as the lead single from their second studio album, Play by Numbers (1982).
"[1] In August 2012, Roger Hart-Wells said "One Perfect Day" came to him one night as he was watching coverage of the 1979 United Kingdom general election, thinking about a beloved girlfriend who had died several months earlier, and had just finished reading a science-fiction novel This Perfect Day by Ira Levin.
[2] In February 2017 Roger Hart-Wells explained how "One Perfect Day" was written about Byron Shire comedian, Sandy Gandhi (1959–2017), and a friend, Carrie Hall.
He told Javier Encalada of The Northern Star, that he was watching the election of Margaret Thatcher in 1979 and thought of how Gandhi and Hall were in the United Kingdom.
