One might revel with leaders, dancing wildly, being a party animal (4,4)
I believe the answer is:
live wire
'party animal' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for live wire that I've seen before include "Alert and enthusiastic person" , "A person with intense energy" , "Very sparky person" , "Life and soul of party" , "isn't it shocking?" .)
