What scouts might have to sing about? (8)
I believe the answer is:
campfire
'what scouts might have to sing' is the definition.
I can't tell whether this definition defines the answer.
'about?' is the wordplay.
I cannot really see how this works, but
'about?' could be 're' ('re' means regarding or about) and 're' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for campfire that I've seen before include "Scout location" , "On which scouts cook and around which they sing" , "Social centre for scouts etc" , "Round which people in tents sing songs" , "where singing is involved" .)
