Hope to include sailors, very good apparently, in lively dance (8)
I believe the answer is:
hornpipe
'lively dance' is the definition.
(dance performed by sailors)
'hope to include sailors very good apparently' is the wordplay.
'to include' indicates putting letters inside.
'sailors' becomes 'RN' (abbreviation for Royal Navy).
'very good apparently' becomes 'pi' (pi can mean overly pious).
'rn'+'pi'='rnpi'
'hope' placed around 'rnpi' is 'HORNPIPE'.
'in' acts as a link.
(Other definitions for hornpipe that I've seen before include "Lively solo dance associated with sailors" , "Lively old sailors' dance" , "Lively jig" , "Obsolete instrument: naval dance" , "piece of music for an > old dance" .)
