Between pub and party regularly muse on suggestive remark (8)

I believe the answer is:
innuendo
'suggestive remark' is the definition.
(I've seen this before)
'between pub and party regularly muse' is the wordplay.
I cannot really see how this works, but
'pub' could be 'inn' (an inn is a type of pub) and 'inn' is located in the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is located in the answer.
'party' could be 'do' (do can informally mean a party) and 'do' is found in the answer.
This explanation may well be incorrect...
'on' acts as a link.
Can you help me to learn more?
(Other definitions for innuendo that I've seen before include "suggestive remarks" , "Malicious suggestion" , "Suggestiveness" , "Aspersion" , "Indirect reference to something rude" .)
