Everyone wanting ogre destroyed quickly (7)
I believe the answer is:
allegro
'quickly' is the definition.
(I've seen this before)
'everyone wanting ogre destroyed' is the wordplay.
'everyone' becomes 'all' (all people).
'wanting' means one lot of letters go next to another.
'destroyed' indicates anagramming the letters.
'ogre' anagrammed gives 'egro'.
'all'+'egro'='ALLEGRO'
(Other definitions for allegro that I've seen before include "Brisk and lively tempo, musically" , "'At a brisk speed, musically (7)'" , "Austin" , "Musical movement using a brisk speed" , "rather quickly" .)
