Socialise with a fair amount of Chicago, for instance, and Elvis touring around island (8)

'socialise' is the definition.
('socialize'->'civilize' is in my internal thesaurus and 'ize'->'ise')

'instance and elvis touring around island' is the wordplay.
'instance' becomes 'ci' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'and' says to put letters next to each other.
'touring' is an anagram indicator (touring can mean moving around).
'around' is an insertion indicator.
'island' becomes 'i'.
'elvis' anagrammed gives 'vilse'.
'vilse' going around 'i' is 'vilise'.
'ci'+'vilise'='CIVILISE'

'with a fair amount of chicago for' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
