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

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

'do the king' is the wordplay.
I cannot quite see how this works, but
'do' could be 'party' (I've seen this before) and 'party' is found within the answer.
'king' could be 'card' (king is a type of playing card) and 'card' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

'and' acts as a link.

Can you help me to learn more?
