Who nosed about in US social events (8)

I believe the answer is:

hoedowns

'us social events' is the definition.
(a hoedown is a type of US dance event)

'who nosed about' is the wordplay.
'about' is an anagram indicator.
'who'+'nosed'='whonosed'
'whonosed' anagrammed gives 'HOEDOWNS'.

'in' acts as a link.

I've seen this clue in The Independent.
