Those curious poker yarns scoundrel initially concocted (4,7)

I believe the answer is:

nosy parkers

'those curious' is the definition.
(people who are very curious)

'poker yarns scoundrel initially concocted' is the wordplay.
'initially' indicates taking the first letters.
'concocted' indicates an anagram.
The first letter of 'scoundrel' is 's'.
'poker'+'yarns'+'s'='pokeryarnss'
'pokeryarnss' with letters rearranged gives 'NOSY PARKERS'.

I've seen this clue in The Times.
