Welsh Clappy Songs????

Question

I heard a Welsh song thing from a welsh friend a couple of years ago. I can't find it on the net. It sounds something like this in Welsh:

Dim dim de.

See See oley oley

minimini aka minimini ey

Ookeraka ookeraka ookeraka eh.

Woo

Answer 1

all welsh songs are crappy.... oh you said clappy, nup dont know any

Answer 2

I don't know of that song maybe you've spelt it wrong

Could it be

Daw ffranc o wlad Awstria i oledd ar y mynydd mawr

Pan ddaeth clamp mawr o eira, a'i bwrw o'n fflat i'r llawr.

Oo, laa, dii, Holiaci ciac holiaci cŵ,

Swis, Swis, Hŵ, hŵ

Holiaci ciac o.

(Note the chorus is meant to imitate yodelling from the Austrians and does not make sense in Welsh, it is just a phonetic al script)
