To lighten things up, this is something related that will amuse you...
What if a band's manager decides a band should continue with NONE Of the members in it?
That actually happened with Fleetwood Mac!
In 1974, manager Davis booked a band called Fleetwood Mac for several dates in America. However, the band that showed up was not Mick Fleetwood and co, but four other people!
Davis claimed that HE owned the named Fleetwood Mac, and if he decided to give it to another four guys, he had every right to. A few lawsuits later, Davis was forced to concede that was not the case.
