Solicitor on ecstasy before party added bells and whistles (6,2)

'added bells and whistles' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'solicitor on ecstasy before party' is the wordplay.
'solicitor' becomes 'pimp' (person who solicits clients for prostitutes).
'on' says to put letters next to each other (in a down clue, letters appear on others).
'ecstasy' becomes 'E' (informal term for the drug).
'before' says to put letters next to each other.
'party' becomes 'dup' (Democratic Unionist Party).
'pimp'+'e'+'dup'='PIMPED UP'

Can you help me to learn more?
