EP band released is sort of potty (6)
I believe the answer is:
'sort of potty' is the definition.
'bedpan' can be an answer for 'potty' (thesaurus). I am not certain of the 'sort of' bit.
'ep band released' is the wordplay.
'released' is an anagram indicator (letters released from their original order).
'epband' anagrammed gives 'BEDPAN'.
'is' is the link.
Can you help me to learn more?
(Another definition for bedpan that I've seen is " Hospital receptacle".)
