A different song of the same name was written by Stevie Nicks for the 1979 album Tusk. Nicks attributed the song to the story of Rhiannon in the Welsh mythological folk story the Mabinogion, and in particular Arawn, who is the great lord of darkness. Nicks' 1974 song "Rhiannon", released on the following year's Fleetwood Mac album, was not based on the Welsh myth but a novel called Triad, by Mary Leader.

The song was released as the fourth single from the Tusk album in The Netherlands, but did not chart.

The musicians on the recording are:

It was included in the setlist for the band's 1980 Tusk world tour, with a St. Louis performance featured in the accompanying Tusk documentary. Stevie Nicks also performed a rearranged version for her 1981 tour in support of her solo album Bella Donna. Nicks played the song once more, at the 1983 US Festival, and the song was not played again by Nicks or Fleetwood Mac.
