Seeraüberin Jenny is from Act 1 of Der Dreigroschenoper (Three Penny Opera) by Bertolt Brecht (words) and Kurt Weill and first performed at the Theater am Schiffbauerdamm, Berlin in 1928.
Along with Polly's Song, Nina Kreft always sang these two songs together. My part was basically that of a stage prop - i.e. to gaze, open-mouthed and enraptured at her performance on centre stage from almost in the wings. For me, those were amongst her best songs and my state of enrapture was genuine. I would beg her to sing it at almost every occasion we met for a musical evening.
The song itself is about Polly Peachum's revenge fantasy in which she is a scullery maid turning pirate queen to order the execution of her bosses and customers.
Seeraüberin Jenny can be found in Die Dreigroschenoper published by Universal Edition.
