Ultan has Asperger's Syndrome, a condition on the autism spectrum that can make it difficult for some people to express themselves in the usual ways.
However, in Ultan's case, there seem to be no such difficulties, as the second video below reveals.
The media studies student at NUI Maynooth is pursuing his dream of releasing a Christmas number one, and has caught the public's collective conscience with Let The Snowflakes Fall.
Now, let's be clear - we're not saying this is the greatest song of all time. But most good Christmas songs are a bit cheesy, right?
Let The Snowflakes Fall has more than a little in common with some of the more recent Christmas songs that the nation has taken to its heart - such as 2003's Christmas Time (Don't Let the Bells End) by The Darkness, or Peter Kay's Once Upon a Christmas Song, released in the guise of Geraldine McQueen in 2008.
It also has some of the most unintentionally hilarious lyrics ever penned, including the instantly infamous line "when that fine morning comes, get out the Christmas plums" (skip to 2:39 above for that gem).
But we're not laughing at Ultan - we're smiling with him. This is an unashamedly upbeat song in the true Christmas spirit, and I for one will always support that.
It's also a man in pursuit of his dream, which makes it a worthy contender not just as a 'Rage Against the Machine' style alternative to The X Factor (that's, like, so 2009), but as a worthy Christmas number one in its own right.
Ultan, good luck from us - we hope you get the top spot when that fine morning comes.
