Let me know if I brought this up before. No doubt question.

During the concert video from this band. In the late 90's...

The singer doesn't sing words during the songs. She sings gibberish at all times.

One exception though, the last song is a version of a beatles song. And it is the beatles very best song by the way.

When she sang that song, it's the only time she sings a song normally.
