Drunken crowd in solemn service (4,4)
I believe the answer is:
high mass
'solemn service' is the definition.
'high mass' can be an answer for 'service' (I've seen this before). I am unsure of the 'solemn' bit.
'drunken crowd' is the wordplay.
'drunken' becomes 'high' (high can informally mean drunk).
'crowd' becomes 'mass' (massing is a kind of crowding).
'high'+'mass'='HIGH MASS'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for high mass that I've seen before include "full service" , "Church service celebrated with music, incense etc" .)
