Waltz son led in place of pride (5,3)

I believe the answer is:

lions den

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

'of pride' is the definition.
The definition suggests a singular noun which matches the answer.

'waltz son led in' is the wordplay.
'son led in' can be anagrammed to 'LIONS' DEN'.
However, I am unsure how the anagram is indicated.

'place' acts as a link.

Can you help me to learn more?

(Another definition for lions den that I've seen is " Danger spot survived by Daniel".)

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