“Buy one, get one free”! “BOGOF” – a marketing strategy now condemned by the environmentally overwrought – is a compelling sales gimmick, for soapsuds, socks (a bit complicated as you actually get 4), even opera.

So, when the Met went further and announced the staging of Puccini’s “Il Trittico” triple bill – “Buy one, get TWO free” – “BOGTF” (I know, it won’t catch on, never win acronym of the year) I was up for it. Love a bargain.

This late, seldom performed, Puccini cornucopia comprises three one act operas at a single sitting: “Il Tabarro”, sleazy action on a barge on the Seine in Paris in 1910; “Suor Angelica”, prejudice and prurience in a convent near Siena in the late 17th century; and “Gianni Schicchi”, greed and farce set in the home of a rich Florentine merchant in 1299. This production placed it in 1959.
