Hopefully this won't get you Knocked Out Loaded before Highway 61 Revisited (3,3,3,4)
I believe the answer is:
one for the road
'highway 61 revisited' is the definition.
I know that 'highway' relates to this answer.
'hopefully this won't get you knocked out loaded before' is the wordplay.
I cannot really understand how this works, but
'you' could be 'one' (I've seen this before) and 'one' is found in the answer.
'out' could be 'forth' (I've seen this before) and 'forth' is found in the answer.
This may be the basis of clue (or it may be nonsense).
(Other definitions for one for the road that I've seen before include "Last drink before going home" , "Individual presumably against railways" , "The ultimate drink" , "Traveller's last drink" , "last order" .)
