Still popular, musical show returning to tour clubs (8)
I believe the answer is:
inactive
'still' is the definition.
(I know that still can be written as inactive)
'popular musical show returning to tour clubs' is the wordplay.
'popular musical' becomes 'evita' (I've seen this in another clue).
'show' becomes 'ni' (I can't justify this - if you can you should believe this answer much more).
'returning' is a reversal indicator.
'to tour' indicates putting letters inside (to tour can mean to go around).
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'evita'+'ni'='evitani'
'evitani' back-to-front is 'inative'.
'inative' enclosing 'c' is 'INACTIVE'.
Can you help me to learn more?
(Other definitions for inactive that I've seen before include "Idle, showing no movement" , "Not moving/working" , "Immobile, not working" , "Passive, doing nothing" , "sluggish" .)
