County where new mother sang in hit (15)

I believe the answer is:

nottinghamshire

'county' is the definition.
(I know that Nottinghamshire is a county)

'new mother sang in hit' is the wordplay.
'new' indicates an anagram.
'mother'+'sang'+'in'+'hit'='mothersanginhit'
'mothersanginhit' with letters rearranged gives 'NOTTINGHAMSHIRE'.

'where' is the link.

(Another definition for nottinghamshire that I've seen is " English county".)

I've seen this clue in The Daily Express.
