British band's transport (5)
I believe the answer is:
bring
'transport' is the definition.
(bringing is a kind of transporting)
'british band's' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'band' becomes 'ring' ('ring' can be a synonym of 'band'**).
'b'+'ring'='BRING'
(Other definitions for bring that I've seen before include "Cause to exist" , "Come along with" , "Convey" , "Get" , "Escort" .)
