Brave siblings untangled neanderthal's leg (6,3,6)

I believe the answer is:

hansel and gretel

I'm a little stuck... Click here to teach me more about this clue!

'brave siblings' is the definition.
The definition suggests a singular noun which matches the answer.

'untangled neanderthal's leg' is the wordplay.
'untangled' indicates an anagram.
'neanderthals'+'leg'='neanderthalsleg'
'neanderthalsleg' anagrammed gives 'HANSEL AND GRETEL'.

Can you help me to learn more?

(Other definitions for hansel and gretel that I've seen before include "children abandoned in forest" , "18 [OPERA]" , "fairy tale" , "Witch-killing pair" , "Fairy story" .)

I've seen this clue in the Sydney Morning Herald.
