salvages

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

'recovers from las vegas revelling' is the definition.
I can't tell whether this definition defines the answer.

'recovers from las vegas' is the wordplay.
'recovers from' indicates an anagram (I've seen 'recovered from' mean this (I've seen this in other clues)).
'las'+'vegas'='lasvegas'
'lasvegas' with letters rearranged gives 'SALVAGES'.

Can you help me to learn more?

(Other definitions for salvages that I've seen before include "Rescues" , "Saves discarded material" , "Saves from fire in Las Vegas" , "dry Eliot piece" .)

I've seen this clue in The Times.
