Have ye all sung and recollected old times? (4,4,4)
I believe the answer is:
auld lang syne
'old times?' is the definition.
(thesaurus)
'have ye all sung and recollected' is the wordplay.
'ye all sung and' anagrams to 'AULD LANG SYNE'.
But, I'm not sure how this is indicated.
Can you help me to learn more?
(Other definitions for auld lang syne that I've seen before include "Old times, especially remembered with affection" , "New Year's Eve ditty" , "Hogmanay song" , "New Year song" , "New Year's Eve favourite" .)
