Nice landing, whirling at hoedown activity (4,7)

I believe the answer is:

line dancing

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

'at hoedown activity' is the definition.
I can't tell whether this definition defines the answer.

'nice landing whirling' is the wordplay.
'whirling' is an anagram indicator.
'nice'+'landing'='nicelanding'
'nicelanding' anagrammed gives 'LINE DANCING'.

Can you help me to learn more?

(Another definition for line dancing that I've seen is " Movement in formation".)

I've seen this clue in The Daily Express.
