Hence, 'Cor blimey!' - 'God blind me!' - is relatively recent and surely much later than the trousers.)
The 'gorblimey' form is much older and the song-line - as I already pointed out - "He wears gorblimey trousers and a little gorblimey hat" was performed in music-hall 20-odd years before the now late and lamented Mr Donegan was even born. He simply modified an already-existing song to create his 1960 hit. By then, of course, 'cor blimey' was the standard version.
None of that detracts from the fact that the question was about trousers and not about songs, anyway. My answer was designed to make clear the fact that the whole concept of these specific trousers - however spelt - is a darn sight older than Lonnie Donegan.
