ok i just listened back - it's the london accent xD nothing else.... it's very very common here to not include or emphasis the final T in words unless you want to sound falsely "posh" - so words like that, carrot, hat, etc all skip the T and have a much much softer t instead. 

The french are allowed to skip letters, why aren't we xD equal rights!!

HAHA must be somethign to do with my EQ settings that reduce the T perhaps, I can assure you I know how to say the word tarrot :D - i'll look into this

thanks for commenting - my regular audiophile xD
