55a) Old fool remaining in US city (5)
N ? D ? Y - is it noddy or neddy or something different as I can't justify
2d) Move quickly when surprised in opening (5) S ? A ? T - is it start? Again can't justify.
Thanks for help.
Further to earlier answer, I think it most be NODDY. The NY is as I said, the 'ODD' could be 'remaining'. But this would leave 'Noddy' meaning 'Old fool' which I haven't heard of
