Just added this on the Lyr req: Londonderry Air thread, and thought I might as well post it here as well, while I'm at it...

I wrote this one a few years ago (not really sure how long ago, so the date below is a guess), just for fun. Thought of the pun and wrote the rest of the song to make it work; it's in Franglais:

London Derrière
© Vikki Appleton Fielden (~2015?)

When Ah was young
Ah left mah 'ome in gay Paris
Ah crossed La Manche
To leeve in Angleterre
To mah soorpreeze
Zee lovely girls of Lohndohn
Sont tres gentil
Et belle beyond compare

So when Ah go to bed
Mah rose Anglaise
Oh voulez vous
Ahccompahnee me zayre
For zo j'adore
Les jolies filles Francaises
Zere's nossing cahn soorpass
a London derriere

(For those who may not know, "la Manche"("the sleeve") is what the French call the English Channel, Angleterre = England and Anglaise = English woman.)
