Take round when the performance has finished (4,4)

I believe the answer is:

show over

I'm a little stuck... Click here to teach me more about this clue!

'take round when' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'performance has finished' is the wordplay.
'performance' becomes 'show' (I've seen this before).
'has' says to put letters next to each other.
'finished' becomes 'over' (similar in meaning).
'show'+'over'='SHOW OVER'

'the' acts as a link.

Can you help me to learn more?

I've seen this clue in The Irish News.
