Work out principal is front man? (10)

I believe the answer is:

figurehead

'is front man?' is the definition.
(I've seen this before)

'work out principal' is the wordplay.
'work out' becomes 'figure' (I've seen this before).
'principal' becomes 'head' (synonyms).
'figure'+'head'='FIGUREHEAD'

(Other definitions for figurehead that I've seen before include "Front man" , "Person without real power" , "Nominal leader without much power" , "carved decoration" , "may be bust" .)

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