A show to see again, we hear (5)
I believe the answer is:
revue
'a show' is the definition.
(revue is a kind of show)
'see again we hear' is the wordplay.
'see again' becomes 'review' ('view' can be a synonym for 'see' so perhaps 'review' is OK for 'see again').
'we hear' shows a homophone (sound like).
'review' is a homophone of 'REVUE'.
'to' is the link.
(Other definitions for revue that I've seen before include "Entertainment with sketches, songs etc" , "Topical variety show" , "Form of light entertainment" , "Evening of songs and sketches" , "Show of sketches, songs, etc" .)
