See song recur about sponge (9)
I believe the answer is:
scrounger
'sponge' is the definition.
(I've seen this before)
'see song recur' is the wordplay.
'song recur' anagrams to 'SCROUNGER'.
Though, I am not sure how the anagram is indicated.
'about' is the link.
Can you help me to learn more?
(Other definitions for scrounger that I've seen before include "Sponge" , "bum" , "Freeloader" .)
