Crossword Genius

A London orchestra as well (4)

Ross

I believe the answer is:

also

'as well' is the definition.
(synonyms)

'a london orchestra' is the wordplay.
'london orchestra' becomes 'LSO' (london symphony orchestra).
'a'+'lso'='ALSO'

(Other definitions for also that I've seen before include "into the bargain" , "Likewise" , "in accompaniment" , "'Besides, moreover (4)'" , "on top" .)

I've seen this clue in The Irish Independent and The Telegraph.
