Rebellious bunch on ecstasy at rave-up in Spanish city (6)
I believe the answer is:
toledo
'spanish city' is the definition.
(I've seen this before)
'rebellious bunch on ecstasy at rave-up' is the wordplay.
'rebellious' is a reversal indicator.
'bunch' becomes 'lot' (synonyms).
'on' means one lot of letters go next to another.
'ecstasy' becomes 'e' (informal term for the drug).
'at rave-up' becomes 'do' (I can't explain this - if you can you should give a lot more credence to this answer).
'lot' in reverse letter order is 'tol'.
'tol'+'e'+'do'='TOLEDO'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for toledo that I've seen before include "Covering, hiding" , "City in central Spain famous for swords" , "Maker of 3 [[COLD STEEL]" , "Spanish city, famous for steel and swords" , "Sp. city, former Visigoth and Castilian capital" .)
