West End composer went ahead and took a trip (9)
I believe the answer is:
travelled
'took a trip' is the definition.
(going on a trip means travelling)
'west end composer went ahead' is the wordplay.
'end' says to take the final letters.
'composer' becomes 'Ravel' (Maurice Ravel).
'went ahead' becomes 'led' (led the way).
The last letter of 'west' is 't'.
't'+'ravel'+'led'='TRAVELLED'
'and' is the link.
(Other definitions for travelled that I've seen before include "Went on a journey" , "Made a trip" , "Journeyed" , "was moving" .)
