From the way it is used in describing the early career of Victor Sylvester, the band leader, it seems to fit your requirement.

The villain of the piece, the true author of the Tower Ballroom's prohibition, was Victor Sylvester. I can still just about remember Sylvester's radio broadcasts, the bland vibrato of the saxophone and the equally passionless tones of the maestro himself monotonously calling out the steps. But until Lionel explained, I had never realized the extent of Sylvester's personal interest in locking dancers into a rhythmic straitjacket.

Before he got his band together, Sylvester was a dance escort. He spent his evenings sitting behind a desk, waiting to earn sixpence from punters who lacked a partner.

This can be somewhat derogatory due to it other meaning:


1. A man who has a continuing sexual relationship with and receives financial support from a woman.
2. A man who is hired as an escort or a dancing partner for a woman.

This question reminds me of a song sung by Tina Turner. It's called "Private Dancer"
