Wayne Newton sang “Danke Schoen” like a ten year old boy. Johnny Carson made fun of this with gay jokes aimed at Newton, who threatened to beat him up.
For the record, Wayne Newton is not gay. But his Vegas act is very, very old, now.
I remember him when he was a thin kid on TV. Then he began to “swell” a little, then bigger then fat as a blimp. His manager shamed him into losing huge amounts of weight and singing in a lower octave.
