who sang what have i done to deserve this
What Have I Done to Deserve This? (song) "What Have I Done to Deserve This?" is a song by English synthpop duo Pet Shop Boys, featuring singer Dusty Springfield.
What's done is done One of the first-recorded uses of this phrase was by the character Lady Macbeth in Act 3, Scene 2 of the tragedy play Macbeth (early 17th century), by the English playwright William Shakespeare, who said: "Things without all remedy Should be without regard: what's done, is done"[2] and "Give me your hand. What's done cannot be undone. – To bed, to bed, to bed!"[3]
