Lived at Wembley Central, even (4)
I believe the answer is:
been
'lived' is the definition.
(I've seen this in another clue)
'at wembley central even' is the wordplay.
'at' means one lot of letters go next to another.
'central' indicates the central letters.
'even' becomes 'e'en' (old-fashioned contraction).
The central letter of 'wembley' is 'b'.
'b' next to 'een' is 'BEEN'.
(Other definitions for been that I've seen before include "(Have) gone in the past (to somewhere)" , "Past participle of be" .)
