Congested, Charlie recorded (7)
I believe the answer is:
clogged
'congested' is the definition.
('clog' can be a synonym of 'congest')
'charlie recorded' is the wordplay.
'charlie' becomes 'c' (phonetic alphabet: alpha, bravo, charlie etc.).
'recorded' becomes 'logged' (logging is a kind of recording).
'c'+'logged'='CLOGGED'
(Other definitions for clogged that I've seen before include "Some morris dancers are" , "Congested, choked" , "Blocked" .)
