Performed with power, Edward (5)
I believe the answer is:
acted
'performed' is the definition.
(acting is a kind of performing)
'with power edward' is the wordplay.
'with' means one lot of letters go next to another.
'power' becomes 'AC' (AC is an example).
'edward' becomes 'ted' ().
'ac'+'ted' is 'ACTED'.
(Other definitions for acted that I've seen before include "Behaved in a certain manner" , "Appeared in play" , "did something!" , "Behaved like thespian" , "participated in panto maybe" .)
