Sir Elton celebrated his number one award with a picture posted from a hospital room, where he is recovering after recently undergoing hip surgery.

The track has recorded 64,000 chart sales and 5.9million streams. It is the first time the singer has had a number one single since he appeared on rapper 2Pac’s posthumous 2005 single Ghetto Gospel.

The Rocketman singer also became the first to have a UK top ten single in six different decades with Cold Heart. His first hit Your Song got to number seven in 1970.
