City pad Sean organised close to LA (8)
I believe the answer is:
pasadena
'city' is the definition.
(Pasadena is a city in California)
'pad sean organised close to la' is the wordplay.
'organised' indicates an anagram.
'close to' says to take the final letters (the close of something is the end).
The final letter of 'la' is 'a'.
'pad'+'sean'='padsean'
'padsean' with letters rearranged gives 'pasaden'.
'pasaden'+'a'='PASADENA'
(Other definitions for pasadena that I've seen before include "US city" , "place in California" , "city in 23 [CALIFORNIA]" , "City in Los Angeles County" , "California city of the Rose Bowl stadium" .)
