Man and a daughter combine to book band for show (9)
I believe the answer is:
headpiece
'book band for show' is the definition.
I can't judge whether this defines the answer.
'man and a daughter combine' is the wordplay.
'man' becomes 'he' (he refers to a man).
'and' says to put letters next to each other.
'daughter' becomes 'd' (genealogical abbreviation).
'combine' becomes 'piece' (I can't justify this - if you can you should give a lot more credence to this answer).
'he'+'a'+'d'+'piece'='HEADPIECE'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for headpiece that I've seen before include "decoration on top" , "Something worn on top" , "Former intellect" , "hat" .)
