I happen to agree with this wholeheartedly. And I have the lyrics (with translation) provided by his daughter (who is married to my nephew!) if anyone is interested.
This version, by Delwyn himself, is a bit easier (for me) to understand the lyrics:
[apparently the original version I had has disappeared, but hereās another, just nothing to watch]:
Iāve just found a new to me artist who does Christmas songs. Just wish I could figure links. Anyway itās Mynediad am ddim.
Letās see if this works:

If you canāt get that, let me know and Iāll see if I can upload an image of it.
Worked brilliantly - thank you so much 
Does anyone have a name of a good Spotify playlist of Welsh language Christmas songs? I find it hard to navigate Welsh language music because I donāt have much vocabulary for musical genres and often the Welsh language music is on a bilingual playlist and I have no idea what to search for (in English or Welsh!) Thanks!
Hereās one from Yws Gwynedd. Though it does contain some English language songs, there are plenty of really great Welsh onesā¦
Otherwise if you just type Dolig or Nadolig in to search on Spotify, there are lots of choices there.
How about this one Theresaā¦
Iāll try and get hold of the lyrics for you.
By the way, the song comes from this CD which includes the lyrics for every song.
Diolch yn fawr that is fab 
No translation unfortunately, but Iāve scanned the words in Welsh for some well-known English carols and for a couple of Welsh carols from the programme for the Welsh carol service in Coleg Yr Iesu/Jesus College in Oxford organised by Cymdeithas Dafydd ap Gwilym: Carolau - Capel Coleg Yr Iesu (ed).pdf (1.3 MB)
and, as I missed out scanning some of the words the first time

You are very welcome. I couldnāt find the lyrics online, so I have attempted to create a transcript, though I donāt understand what theyāre saying about the monkey and the stuffing?!
Dymunwn Nadolig llawen
Dymunwn Nadolig llawen

Dymunwn Nadolig llawen

A thatws a pys a grefi
A stwffin [ da-da-da] mwnci

A phawb yn y tÅ·
Dymunwn Nadolig llawen
I bawb yn y byd
One of my favourites - so beautiful!
Hereās a lovely treat for you from the very talented harpist who played at the SSiW 10th birthday party in The Galeri, Caernarfon earlier this yearā¦
Thereās an Al Lewis song I donāt have? This wonāt do at all, I must remedy this problemā¦
Iāve just heard Bryn Terfel on Radio3 singing āTawel Nosā. Pure magic: that voice and that language!
Thank you for reviving this thread!
Conductor, composer and arranger of music Gilmor Griffiths, from Ponciau near Wrexham, was the head of the Music Department of Ysgol Glan Clwyd, Llanelwy for 26 years.
In 1981 a Christmas LP was released called āNos Nadolig Ywā. The LP contained traditional carols as well as songs written and composed by Gilmor. The songs were sung by the choirs of Llanelwy school and recorded at Llanelwy Cathedral. The LP soon became one of Walesā best-loved Christmas albums and is still popular today.
The album contains an enchanting collection of haunting carols as well as more upbeat songs and it is the perfect accompaniment for an evening by the light of the Christmas tree.

Did you know that one of the most famous Christmas carols, Deck the Halls, originated from a Welsh dancing song?
The melody dates back to the 16th Century and it is believed to have been part of the Welsh winter carol called āNos Galanā (which means New Yearās Eve).
The English lyrics were written by a Scottish musician called Thomas Oliphant in 1862.
