As well as the song being sung in the original four parts by many choirs, the top melody line by itself has also become a solo love-song. A hundred years after it was first published
Ryan Davies performed the song at the
Swansea Top Rank introducing it as "the greatest love song ever written". A live recording of this version was included on Davies' album
Ryan at the Rank and quickly became one of Davies' most notable and familiar performances. Davies' rendition began a renewed popularity for the performance of the song, especially with
Welsh Male Voice Choirs. Two of the most widely recognized choral renditions are by the
Treorchy Male Voice Choir, and the Neath Male Voice Choir. The song is often performed at the
Principality Stadium during the
Welsh rugby team's home matches, and the
Morriston Orpheus Choir recorded a version of the song for the
Welsh Rugby Union's official album in 2006.
John Cale has performed the song throughout his career, most notably a 1992 TV performance on the
S4C programme
Heno. Opera singer,
Bryn Terfel recorded a choral version of the song on his album "We'll Keep a Welcome".
Cerys Matthews recorded a guitar version for her 2010 album
