I saw Robert and Elizabeth at the Chichester revival and I can only imagine that the original was a much better production. The leads were underwhelming singers where great voices are called for. I doubt it would have played well on Broadway in the 1960s, too old operettaish when audiences were rejecting the style. The D'Oyly Carte Opera did several american tours around this time with the same strong casts that recorded the stereo versions of all the operettas on Decca London and yet the tours were only moderately successful. Another few years and the company stopped american tours for lack of box office. Robert and Elizabeth belonged at City Opera which was doing these kind of things at the time. Now only Ohio Light Opera is the only place I could imagine tackling it, but they are never able to produce two thrilling leads capable of making the piece take off. Despite the incredible score, it is too out of date and was even 60 years ago. Sit back, enjoy the great cast album.
