It certainly is, Ruth. I first heard this in a R3 broadcast from Buxton, with Thomas Allen as Hamlet. Wonderful stuff.
Although it was written in 1868, Ambrose Thomas had to write a new ending the following year for Covent Garden, as it was thought that a happy ending to Hamlet might not go down too well with British audiences. It still flopped.

Here's another quintet of operas to spot plus a link to identify. The clips should be a little easier than yesterday's!

I am at home, awaiting a delivery - and trying not to allow the prospect of a fiendish quiz to distract me from getting some bluddy paperwork done.  I think it's a losing battle ..... 

Oh, all right.  The work can wait.  Sendspace is proving a little recalcitrant today but:

01 Something by Gluck?  
02  
03 Strauss Arabella - Aber der Richtige
04 Verdi Rigoletto Act IV
05 Wagner Das Rheingold - Fafner killing Fasolt in Scene 4

03 and 04 had me thinking that there was a cross-dressing connection - Zdenka in Arabella is dressed as a boy to save the Waldners the expense of bringing her out in Viennese society, while in Act IV of Rigoletto, Gilda is dressed as a boy.  But the Rheingold link scuppers that - unless this is an obscure reference to Fafner turning himself into a dragon (which, as Donington assures us in Wagner's Ring and its Symbols, is a symbol of the Eternal Mother ....) ... no, I don't think I can make that one fly.  Sometimes a dragon is just a dragon.

Edit to provide the right scene number from Das Rheingold.

Damn! Arabella and Rheingold would have been the only ones I'd have recognised. I think I may have to bring the general Repertoire Test back into being soon. (Without the points system of course.)

So, we now have:

6 - Tchaikovsky - Evgeny Onegin
7 - Verdi - Il Trovatore
8 - Wagner - Die Walkure

Which leads me to a sibling link

3 - Aber der Richtige is a duet between Arabella and Zdenka, who are sisters
4 - In Act IV of Rigoletto, we see Sparafucile and Maddalene, who are brother and sister, arguing over whether to kill the Duke
5 - Das Rheingold - the clip is of Fafner killing his brother Fafner
6 - The clip is of the opening scene of Evgeny Onegin, in which Tatiana and Olga sing a duet while their mother and grandmother make jam;
7 - Il Trovatore - the Count of Luna and Manrico are of course brothers, following Azucena's mix-up with the babies all those years ago
8 - Die Walkure - the clip is of Siegmund and Sieglinde, the twins, at the moment at which incest is moving rapidly up the agenda, so to speak

In all these cases there are overtones of discord and disharmony between the siblings (Onegin flirts with Olga having turned down Tatiana and kills Olga's lover in a duel) apart from Die Walkure, where the siblings are a bit too close for comfort ...

Die Walkure again - Act III is full of sisters (and their Dad).
Elektra - Elektra, Orestes and Chrysanthemum (or whatever her name is).
Cosi Fan Tutte - two more sisters.
Werther - yet more sisters.

And probably many more!
