It may or may not be a well-known English song I may or may not have translated into a language I may or may not have invented.
The meter isn't good, but the rhyme scheme is pretty close.
Dansar Andthilin
Andthilin, Andthilin
Me and anden an thilin
Grat sten silin thilen
An thicori dari thalen
Heimer!
Har muiren me Andthilin
Grat orn?
Danleiden mnor
Ucro siler an mor
Gaen aden tul?
Sileiden vul
Heimer, behan!
Behad muiren me Andthilin
Ad ancloa ebon
Ad darad
An venar abon
Han muiren aden behad
Andthilin, Andthilin
Falche haroan Andthilin
Grat sal grat ariche
Be thal
Aden thria sal
Ad grat thria
Theinen thia
Beileiden me Andthilin
