Dean's crowd reviewed steps taken by Highlanders, say (5,5)

I believe the answer is:

sword dance

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

'steps taken by highlanders say' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.

'dean's crowd reviewed' is the wordplay.
'reviewed' indicates an anagram (letters reviewed or revised).
'deans'+'crowd'='deanscrowd'
'deanscrowd' is an anagram of 'SWORD-DANCE'.

Can you help me to learn more?

(Other definitions for sword dance that I've seen before include "Performance involving sharp weapons" , "Potentially dangerous steps" , "Movement involving cutlass" , "Pre-war ritual" , "steps with much arm-waving" .)
