Paradise Island? Yes, life is sorted! (7,6)

I believe the answer is:

elysian fields

I'm a little stuck... Click here to teach me more about this clue!

'paradise' is the definition.
I know nothing about this answer so I can't judge whether this works.

'island? yes life is sorted' is the wordplay.
'is sorted' indicates anagramming the letters.
'island'+'yes'+'life'='islandyeslife'
'islandyeslife' with letters rearranged gives 'ELYSIAN FIELDS'.

Can you help me to learn more?

(Other definitions for elysian fields that I've seen before include "(Mythological) Abode of the dead" , "state of perfect happiness" .)

I've seen this clue in The Independent.
