Where to take off songs written by Journey? (8)
I believe the answer is:
airstrip
'where to take off' is the definition.
(where an aircraft takes off)
'songs written by journey?' is the wordplay.
'songs' becomes 'airs' (I've seen this before).
'written by' is a charade indicator (letters next to each other).
'journey?' becomes 'trip' (trip is a kind of journey).
'airs'+'trip'='AIRSTRIP'
(Other definitions for airstrip that I've seen before include "possible starting place" , "Small runway" , "Small landing-place" , "Small flying field" , "(Unprepared) runway" .)
