Tour worker (6)
I believe the answer is:
roadie
'tour worker' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for roadie that I've seen before include "Touring musicians' gofer" , "Touring band's supporter" , "Touring band's worker" , "Person moving and setting up band's equipment" , "Band's assistant" .)
