On the CD the first part of Act III is labeled: Opening Ballet WaltzThis is a little misleading. What is known as the Act III Waltz is the second part of the opening where it appears on the CD. This is followed by the Ballet. In the original the second half of the Ballet is an instrumental of 'Just We Two'. On the CD the first part of the Ballet is labeled 'Ballet' and a much extended 'Just We Two' is labeled 'Waltz'. This is, in fact, the second half of the Ballet although much longer than the original on this recording. It is possible this extended version was used this way in a revival.
