Silence on the radio or the funeral march? (4,3)
I believe the answer is:
dead air
'silence on the radio or the funeral' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'march?' is the wordplay.
I cannot really understand how this works, but
'march?' could be 'dead' (dead march is a kind of march) and 'dead' is located in the answer.
The remaining letters 'air' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for dead air that I've seen is " Silence on radio".)
