Yes I have seen this at the Royal Opera. As Manon is seldom staged, I grasp the opportunity to see it at the Metropolitan Opera. At the helm was Fabio Luigi who brought this lush score to live. Anna Netrebko, as Manon, was fabulous - from the innocent little girl to the temptress par excellence - though the seduction scene in St Sulpice was, ahem, a bit over done - I didn't remember seeing Manon in the Royal Opera production acting like a nymphomaniac!
I quite forgot the first number in Porgy and Bess is Summertime! Beautifully sung by Nicole Cabell as Bess. On a whole, the chorus number was better sung than the solo numbers - where the diction was generally inadequate. The set (Michael Yeargan) was three-dimensional and worked really well with the many scenes in this work. John Wilson was in his elements in the pit and the orchestra responded with a rhythmic boisterous sound - the best part of the evening.
