Group for example, east European, appearing in Greek city (3,3,4)

Ross

I believe the answer is:

the bee gees

'group' is the definition.
(musical group)

'example east european appearing in greek city' is the wordplay.
'example' becomes 'eg'.
'east' becomes 'e' (synonyms).
'european' becomes 'e' (abbreviation e.g. EU).
'appearing in' indicates putting letters inside.
'greek city' becomes 'thebes' (I've seen this before).
'eg'+'e'+'e'='egee'
'egee' going within 'thebes' is 'THE BEE GEES'.

'for' is the link.

I've seen this clue in The Times.
