I am hoping to get some explanation as to why the particular answer to 1a changes to the particular name that is the grid entry. If all that is going on here is that random entries that happen to be 'things' are replaced by random names, then that would be very lame. I have to believe something more is going on. Are the 10 names all characters in some show? book? band? Famous people whose last names are connected to the clue answers?
