[5] That version is one of fewer than fifty singles to have sold more than ten million physical copies worldwide.

[6] The original recording of the song by Lally Stott was first released in September 1970 in Italy, where he had been living for several years.

The record company, Philips, was reluctant to release it overseas, and offered it to two other groups: Scottish folk-pop group Middle of the Road, who were working in Italy at the time, and the Trinidadian brother-and-sister duo Mac and Katie Kissoon.

The song's title has sometimes been parodied: Included on the soundtrack in The Guard (2011) performed by Middle of the Road.

The character Frank Gallagher references the Middle of the Road version in an episode of the UK TV series, Shameless Included on the soundtrack of the Shudder exclusive film, "The Power" (2021), which takes place in 1974 London.
