Organ's no longer right with endless beer (6)

I believe the answer is:

lienal

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

'organ's no longer' is the definition.
I can't tell whether this defines the answer.

'right with endless beer' is the wordplay.
'right' becomes 'lien' (legal right).
'with' says to put letters next to each other.
'endless' means to remove the last letter.
'beer' becomes 'ale' (type of beer).
'ale' with its final letter taken away is 'al'.
'lien'+'al'='LIENAL'

Can you help me to learn more?

(Another definition for lienal that I've seen is " of spleen".)

I've seen this clue in The Times.
