Sounds like one of The Beatles is lucky and charming perhaps (6)
I believe the answer is:
scarab
'the beatles is lucky and charming perhaps' is the definition.
I can't tell whether this definition defines the answer.
'sounds like one' is the wordplay.
I cannot really see how this works, but
'one' could be 'a' and 'a' is found within the answer.
The remaining letters 'scrab' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for scarab that I've seen before include "Beetle considered divine by ancient Egyptians" , "Beetle revered by ancient Egyptians" , "Sacred Eygptian beetle" , "Beetle, considered to be divine in ancient Egypt" , "Old abuse" .)
