"Beautiful Sunday" is a song written by #DanielBoone (real name Peter Charles Green) and Rod McQueen (real name David Balfe) and performed by Boone. It appeared on his 1972 album Beautiful Sunday and was produced by #LarryPage and arranged by Boone. It has been described as the biggest international hit in the British #bubblegumPop genre. Robin Carmody of #FreakyTrigger praised the song for its "timelessly, wonderfully obvious #chordSequence" and euphoric tone.

My own reflection on the date made me think of this opening to a review I wrote for #FreakyTrigger in late July 2001. Glib on multiple levels of course (the second paragraph was more about the joys of then-current pop). But I remember why I wrote that next-to-last sentence, and then it came true. Full piece if you'd like to read it -- I do still stand by the second paragraph at least: https://freakytrigger.co.uk/ft/2001/07/lateralus
