40. ????

One act is going to be added for the injury to the russian bar trio. That is listed as the wild card act and the people up for it are at the bottom of the eliminated list. There's a never before seen act with three children (yodeling?) and one of them playing the double bass. Maybe I missed something. Other than that, only 1 act is missing and all of the televised dismissials are accounted for (except for the older gentleman keyboardist.)
