Was hard to be upset after Little Richard towed vehicle (8)
I believe the answer is:
rickshaw
'vehicle' is the definition.
(rickshaw is a kind of vehicle)
'was hard to be upset after little richard' is the wordplay.
'hard' becomes 'h' (abbreviation used in pencil classifications).
'to be upset' indicates an anagram (I've seen 'are upset' mean this).
'after' is a charade indicator (letters next to each other).
'little richard' becomes 'rick' (short for Richard).
'was'+'h'='wash'
'wash' anagrammed gives 'shaw'.
'shaw' after 'rick' is 'RICKSHAW'.
'towed' is the link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for rickshaw that I've seen before include "Two-wheeled hooded carriage" , "vehicle using manpower" , "Two-wheeled cart" , "foreign conveyance" , "Man-powered transport" .)
