Friend takes in European show (7)
I believe the answer is:
matinee
'show' is the definition.
(matinee is a kind of show)
'friend takes in european' is the wordplay.
'friend' becomes 'mate' (mate is a kind of friend).
'takes' means one lot of letters goes inside another.
'european' becomes 'E' (abbreviation e.g. EU).
'mate' placed around 'in' is 'matine'.
'matine'+'e'='MATINEE'
(Other definitions for matinee that I've seen before include "sort of jacket" , "in which players may appear?" , "First jackets" , "Daytime performance of play etc" , "Afternoon showing of play" .)
