Today there are similar reports, although it’s important to get your Welsh right. A lot of songs about blackbirds in Welsh, apparently.
So, to clarify:
The Welsh tune in question is not, as reported here, A Ei Di’r ‘Deryn Du, which is a very, very nice tune, in fact probably superior to Wele ti’n eistedd aderyn du?, but not the same as Kookaburra at all, and you can hear it here.
It’s also not Aderyn du – you know, the one that goes “Aderyn du ai blufyn sidan, ei big aur ai dafod arian / Ei di drosta i i Gydweli …” Here’s a pretty girl singing that one:
Instead, Wele ti’n eistedd aderyn du? sounds like this (but see the comment below from Anthony Linden Jones):
I now request that one of Australia’s more smart-arse bands (I’m looking at you, TISM) record a patriotic song with lots of flute quotations in the background, from all the Welsh blackbird songs.
Meanwhile, is there nothing but our wretched national anthem that we can claim as our own?
