Morrison's delivery vehicle (3)
I believe the answer is:
van
I believe this is a double definition.
'morrison's' is the first definition.
(musician Van Morrison)
'delivery vehicle' is the second definition.
(I've seen this in another clue)
(Other definitions for van that I've seen before include "Light vehicle" , "Business vehicles or army front" , "Leading part" , "Transporting vehicle" , "Army front or business vehicle" .)
