Try this one for the Irish National anthem (amhrainn na Bfiann) It's my first try so bear with me:

Shin,up Fiona Foyle

A tall fair gal in hairnets

Been there too, her teen a raw egg whoring

Fay Woad bets fair

Shan-dy or Ginger faster

Knee wobbler faints Tiernan or faints Paul.

A mucked-up Haymes or Barney Whale,

Leg gone in Gale, come boys for sale

Le gunners spake a lot of cobb-lers

So live coming, Ow Ron, Navyyyy
