(and) Queen Anne is dead too

Meaning
your news is stale; we all know this
Example He was trying to explain that the churches had lost a lot of influence in modern society, when some joker shouted out ‘And Queen Anne’s dead too!’
(Note A rather old-fashioned saying used as a refrain, rather like ‘and the band played on’, or ‘tell us something new’ but with a slightly different sense.)
