Say the name on cue, for a change (8)
I believe the answer is:
announce
'say' is the definition.
(announcing is a kind of saying)
'the name on cue for a change' is the wordplay.
'the name' becomes 'ann' (**).
'for a change' is an anagram indicator.
'on'+'cue'='oncue'
'oncue' is an anagram of 'ounce'.
'ann'+'ounce'='ANNOUNCE'
(Other definitions for announce that I've seen before include "Publicise" , "Declare her weight" , "Make known publicly or to an audience" , "Disclose" , "Reveal" .)
