Well, I've found them ... there's several of them. They are in the book of the 1968 Eisteddfod ( Y Barri a'r Fro) ... here's a little selection, including the two joint prizewinners. They had to write an " Englyn Digri" and the theme was "Banana" (!)
Traditionally competitors use a "Ffug-enw" ... as you will see ....
Heno eto nit-wit - a'i dropodd
Yn drap ar y concrit ;
Herbie a aeth mewn orbit
Yn nisplei'r ' banana split'
Nit-Wit
Yn ei chell mae hi'n gwella, - ei choes
Yw ei chwyn ran amla' ,
O yrru'r ieir ar iâ
Bu nain ar groen banana.
John Tw
Wên inne'n foi banana - nes cwympo
Ar y scamp 'os dwetha i ;
We twist, ŵ , yn 'i bŵa,
A dima down i'r dom da.
Castell Martin
Anlwcus ! O flaen y Local - syrthiais
Yn swrth ar un feddal ;
Syndod i'r Duwdod oedd dal
Hen sant yn horisontal .
Hen Sant
Those last two were the joint prizewinners.
So .. in case you struggled to find some of the "rules" about englynion, you've got a few more to go on.
And now, music, brought to you by LWi88Y Enterprises .... here's Jen Jeniro and "Powys" ..
