Singer's very nearly changed name (4,4)
I believe the answer is:
vera lynn
'singer's' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'very nearly changed name' is the wordplay.
I cannot quite see how this works, but
'very' could be 'v' (abbreviation) and 'v' is found within the answer.
an anagram of 'nearly' is 'eralyn' which is located in the answer.
'name' could be 'n' (common abbreviation e.g. on forms) and 'n' is found within the answer.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for vera lynn that I've seen before include "Singing Dame of WWII" , "White Cliffs of Dover singer, b.1917" .)
