In 2015, Newton-John was a guest judge on [[Glamazonian Airways|an episode]] of ''[[RuPaul's Drag Race]]''.

The song was a re-imagining of her 1980 single "Magic", which she noted was to celebrate both the 35th anniversary of ''Xanadu'' and as a dedication to her daughter. About the latter, Newton-John stated: "I met Chloe's dad on the set of ''Xanadu;'' so, without that film, Chloe wouldn't be here.
