Remember being concerned with visit (6)
I believe the answer is:
recall
'remember' is the definition.
('recall' can be a synonym of 'remember')
'concerned with visit' is the wordplay.
'concerned with' becomes 're' (**).
'visit' becomes 'call' ('call' can be a synonym of 'visit').
're'+'call'='RECALL'
'being' acts as a link.
(Other definitions for recall that I've seen before include "Summon back or bring to mind" , "Hark back" , "Summon back, perhaps to mind" , "Recollect" , "Get back" .)
