Hero's recast in musical, giving a bit of a bow? (9)
I believe the answer is:
horsehair
'a bit of a bow?' is the definition.
I can't judge whether this definition defines the answer.
'hero's recast in musical' is the wordplay.
'recast' indicates an anagram.
'in' indicates putting letters inside.
'musical' becomes 'hair' (1960s musical).
'heros' anagrammed gives 'orseh'.
'orseh' inserted inside 'hair' is 'HORSEHAIR'.
'giving' is the link.
Can you help me to learn more?
(Other definitions for horsehair that I've seen before include "Natural fabric used in stuffing upholstery" , "this may provide us with many strings to our bow" , "substance, stranded" , "material for stuffing" , "It's used in furniture for padding" .)
