 FACT: After the first movement of Mozarts Symphony No. 40, the  concert goes to the interval. While it has been known for a concert  to include, for example, a single aria from a whole opera, it is  never the case that a concert includes only, as in this case, the  most famous movement, an extract, from a whole symphony. (Or, if  there are any concerts like this, they would not be attended by the  social elite, as depicted here.)
