Sally Army with performance for another world! (6)
I believe the answer is:
saturn
'another world' is the definition.
(another planet)
'sally army with performance' is the wordplay.
'sally army' becomes 'SA' (abbreviation for Salvation Army).
'with' is a charade indicator (letters next to each other).
'performance' becomes 'turn' (turn is a kind of performance).
'sa'+'turn'='SATURN'
'for' is the link.
(Other definitions for saturn that I've seen before include "Turn as a planet" , "Sixth rock from the sun" , "orbits the sun" , "Solar system planet" , "tried to pass vessel" .)
