Do the king and queen attend? (4,5)

'queen attend?' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'do the king' is the wordplay.
I cannot really see how this works, but
'do' could be 'party' (I've seen this before) and 'party' is found in the answer.
'king' could be 'card' (king is a type of playing card) and 'card' is present in the answer.
No letters remain.
This explanation may well be incorrect...

'and' is the link.

Can you help me to learn more?
