What a difference a /d/ makes

My suspicion is that this gaffe is partly down to the propensity for Brits to adopt Americanisms into their singing accents. As is well-known, many north Americans do not phonetically distinguish post (or inter?)-vocalic /t/ and /d/ -turning them both into a flapped 'r'. This gave rise to difficulties in the recent England match against Croatia where a Brit sang the croatian national anthem and made a pronunciation error.

According to the lyrics posted here, the second quatrain of the Croatian national anthem should go as follows:
Mila kano si nam slavna,
Mila si nam ti jedina,
Mila kuda si nam ravna,
Mila kuda si planina!
Dear, you are our only glory,
Dear, you are our only one,
Dear, we love your plains,
Dear, we love your mountains.

However, Mr. Henry rendered two repetitions of 'kuda' in the last two lines as 'kura'. ... he instead sang 'Mila kura si planina' which can be interpreted as 'My dear, my penis is a mountain'.

Apparently, the chuckle that gave the Croatian players has been given as one reason for their winning the game.
