Concerning the TOD, I agree with DR Charles Pogue; I have too many favorite plays and my whims change daily. If I'm feeling partial to Restoration and 18th Century comedy, it's this:
1. THE COUNTRY WIFE
2. THE SCHOOL FOR SCANDAL
3. SHE STOOPS TO CONQUER
If it's classic American 20th Century dramatic literature, I guess it would be:
1. A STREETCAR NAMED DESIRE
2. LONG DAY'S JOURNEY INTO NIGHT
3. AH, WILDERNESS
But on another day I might say iit's MARAT/SADE, WHAT THE BUTLER SAW, and ARSENIC AND OLD LACE!
But, of all the plays ever written, I guess number one for me is KING LEAR, now and forever.
I have the same problem with opera.
Is there an opera of KING LEAR? And if so, by whom?
There have been several operatic versions. according to GROVE'S DICTIONARY OF OPERA:
Cordelia (1854) by Semeladis
Il re Lear (1883) by Ghislanzoni
Le Roi Lear (1888) by Raynaud
Cordelia (1913) by Cottrau
Re Lear (1939) by Frazzi
Koenig Lear (1955) by van Durme
Koenig Lear (1956) by Gerhard
Lear (1978) by Reimann
There are several more. Both Verdi and Benjamin Britten wanted to write operas based on the play. The Reimann opera was recorded after its 1978 premiere.
