Hi,
incorrect formation of a sentence? i see. thank you.
if you may allow me, they should be rewritten as:
the lad from belfast; the one and only george best and he is a genius.
the legend of christmas; the one and only santa clause and he is great.
These are still incorrectly formed sentences. It's like writing 'The table and it is round'. Would you say that is a correct sentence? I'd say 'The table is round'.
I'd also say 'The lad from Belfast, the one and only George Best, is (was? didn't he die?) a genius'.
Best wishes again, Clive
