In this Christmas edition, we dive into the real story behind Wham’s Last Christmas — the melody George Michael wrote in a spare bedroom at his parents’ house, arranged and performed almost entirely by himself, then gave away in charity royalties without ever asking for credit. Generation after generation kept rediscovering the song until it stopped being a single… and became a holiday tradition. And to show just how far it traveled, we run through five of the biggest artists who recorded their own versions — Taylor Swift, Kelly Clarkson, Ariana Grande, Jimmy Eat World, and Gwen Stefani — each adding their own stamp to a timeless classic.
