Olivia Newton-John: The Photo Archive Xanadu

Who doesn’t like to listen to some good old Olivia Newton-John on a summer day? Her catalogue is a showcase of timeless songs as Boston alt-rocker Juliana Hatfield proved with her recent record covering the English-Australian singer tunes.

One of the hits featured on the refreshing Juliana Hatfield Sings Olivia Newton-John album is ‘Physical’, a tune named The Sexiest Song Of All Time at Billboard.com on this exact day in 2012. 'Physical' is still inspiring a lot of pop acts nowadays, you just have to listen to the song with the same name featured on the last Dua Lipa LP.

Today we’re looking at photographs of the ‘Physical’ era as well as some snaps of Olivia Newton-John starring in Grease and Xanadu, with some pics of the singer swimming with dolphins in the sea (you can’t get a more summery picture than that!).
