Actors on tour platoon picked up (6)
I believe the answer is:
troupe
'actors on tour' is the definition.
'platoon picked up' is the wordplay.
'platoon' becomes 'troop'.
'picked up' shows a homophone (sound like).
'troop' sounds like 'TROUPE'.
(Other definitions for troupe that I've seen before include "Dance company" , "Our pet (anag) - company of performers" , "Group of travelling actors" , "Theatre company" , "Travelling company of performers" .)
