Can see about spiritualist’s meeting (6)
I believe the answer is:
seance
'spiritualist's meeting' is the definition.
(I've seen this before)
'can see about' is the wordplay.
'about' indicates an anagram.
'can'+'see'='cansee'
'cansee' with letters rearranged gives 'SEANCE'.
(Other definitions for seance that I've seen before include "Dead-contacting session" , "Some may arrive late to this meeting" , "Spiritualist meeting, all hold hands" , "Meeting for communicating with spirits" , "Dead-contacting meeting" .)
