Sonnet 138 by Suchet.

I heartily recommend this extract from a 1979 master class conducted by Trevor Nunn for an audience of enthusiastic students.

In the extract, Nunn leads David Suchet through Shakespeare's Sonnet 138 (one of the twenty-five sonnets which I recite from memory twice a day every day). For those who are familiar with Suchet mainly from his roles in popular television and films, I should note that he was and is a brilliant Shakespearean actor -- as is evident from his rendering of the sonnet at the end of this clip.
