Dad’s Army, right for Elvis, say? (3,4)
I believe the answer is:
pop star
'elvis say?' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'dad's army right' is the wordplay.
'dad's' becomes 'pops' ('pop' can be a synonym of 'dad').
'army' becomes 'ta' (abbreviation for Territorial Army).
'right' becomes 'r' (common abbreviation).
'pops'+'ta'+'r'='POP STAR'
'for' is the link.
Can you help me to learn more?
(Other definitions for pop star that I've seen before include "Popular singer" , "Chart musician" , "Musical celebrity" .)
