In his stage shows in later years, he would include a segment with opera singer Marylyn Mulvey. She would try to sing an aria, and he would react and interrupt, with such antics as falling off the bench in "surprise" when she hit a high note. He would also remind her repeatedly not to rest her hand on the piano, telling her that if she got used to it, "and one day a piano was not there – "Fffftttt!" " After the routine, the spotlight would rest on Mulvey, and she would sing a serious number with Borge accompanying in the background.
