Satisfy audience about tense gathering of legislators (10)

I believe the answer is:

statehouse

'gathering of legislators' is the definition.
(where state legislators gather)

'satisfy audience about tense' is the wordplay.
'satisfy' becomes 'sate' (I've seen this in another clue).
'audience' becomes 'house' (term for a theatre's audience).
'about' is an insertion indicator.
'tense' becomes 't' (abbreviation used in many dictionaries).
'sate'+'house'='satehouse'
'satehouse' placed around 't' is 'STATEHOUSE'.

I've seen this clue in The Independent.
