Ending with fellow at home having beer (6)
I believe the answer is:
finale
'ending' is the definition.
(I know that finale is a type of ending)
'fellow at home having beer' is the wordplay.
'fellow' becomes 'f' (abbreviation - of a society etc.).
'at' says to put letters next to each other.
'home' becomes 'in' ('he's home' can mean 'he's in').
'having' is a charade indicator (letters next to each other).
'beer' becomes 'ale' (type of beer).
'f'+'in'+'ale'='FINALE'
'with' acts as a link.
(Other definitions for finale that I've seen before include "Last part of something" , "Conclusion, end" , "Ending" , "Last song etc" , "Last section of a musical composition" .)
