Help and aid distributed for London theatre (7)

I believe the answer is:

adelphi

'london theatre' is the definition.
(I've seen this before)

'help and aid distributed' is the wordplay.
'and' means one lot of letters go next to another (I've seen this in other clues).
'distributed' is an anagram indicator.
'help' put after 'aid' is 'aidhelp'.
'aidhelp' anagrammed gives 'ADELPHI'.

'for' acts as a link.

(Another definition for adelphi that I've seen is " London theatre".)
