These are three great animated classics. Unfortunately, my enjoyment of The Wrong Trousers (the best of the three) was spoiled by the fact that the music had been changed in places, presumably due to the idiot copyright laws. Instead of 'Happy Birthday', Gromit's card now plays an uninspired version of 'For He's A Jolly Good Fellow'. The penguin's radio still starts playing 'Tie A Yellow Ribbon', but in place of 'Happy Talk' and 'How Much Is That Doggie In The Window', we get what seems to be generic electronic organ noise, on what is obviously a different organ. This being issued by the BBC, the changes were doubtless done as cheaply as possible. That said, the most thrilling chase in television history still involves a bald inventor, his dog and an armed penguin racing around a living room on an electric train set. Full marks to Aardman, but not BBC Worldwide.
