So, a chosen few can be forced to make an appearance (4,4,4)

I believe the answer is:

show ones face

'make an appearance' is the definition.
(to show one's face is to appear at an event)

'so a chosen few can be forced' is the wordplay.
'can be forced' indicates an anagram.
'so'+'a'+'chosen'+'few'='soachosenfew'
'soachosenfew' anagrammed gives 'SHOW ONES FACE'.

'to' is the link.

I've seen this clue in The Independent.
