I'm in the midst of reading an excellent history of Stax Records called Respect Yourself. Robert Gordon is the author. In the book he talks about how in the late 60s/early 70s, how Stax employed a man named Johnny Baylor to promote their records. Baylor and his team were not above using threats of violence and gun play in their efforts to ensure Stax releases got radio play.

This leads me to wonder how far did Motown promotion heads went to get Motown records airplay? Does anyone know if they engaged in similar tactics as Baylor did with Stax?
