Reelz has previously aired Elton John: The Nation's Favourite Song, but will have a rerun this weekend.
The broadcast first aired on ITV in November, part of the channel's regular music countdown series. Besides rich archive footage, it contains interviews with the Rocket Man himself; Sting; Billy Joel; Sharon Osbourne; Annie Lennox; Ed Sheeran; Lionel Richie, and many others.
If you missed this, or wish to watch it again, Reelz will repeat the programme tomorrow morning, at 7:30 a.m. ET.
