Singer, elderly, confused about love (8)
I believe the answer is:
yodeller
'singer' is the definition.
(yodeller is a kind of singer)
'elderly confused about love' is the wordplay.
'confused' is an anagram indicator.
'about' means one lot of letters goes inside another.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'elderly' is an anagram of 'ydeller'.
'ydeller' placed around 'o' is 'YODELLER'.
(Other definitions for yodeller that I've seen before include "Alpine singer" , "Mountain air for him" , "Singer using falsetto" , "Vocalist" .)
