'left alone' is the definition.
'isolated' can be an answer for 'alone' (similar in meaning). I'm not certain of the 'left' bit.

'oldies at dance' is the wordplay.
'dance' is an anagram indicator.
'oldies'+'at'='oldiesat'
'oldiesat' anagrammed gives 'ISOLATED'.

(Other definitions for isolated that I've seen before include "Alone, set apart" , "(Left) on one's own" , "Placed alone" , "Single" , "Segregated" .)
