Oftentimes the rights to the name of the band is bought and sold among the surviving members just like any other piece of property. Sometimes the eventual owner of the name wasn't in the original band, hires other people who were never in the original band, but still have the right to call themselves by the band's original name.
Methinks that the good Virignia lawmaker got sucked in at the State Fair last year.
In the late 1980s, when the band was officially defunct, former Yes-men Jon Anderson, Rick Wakeman, Bill Bruford and Steve Howe got together, recorded an album and prepared to tour, calling themselves "Yes." Squire sued them successfully and his sole right to the band's name (a dictionary word, for all that) was established in the courts.
So the act released the album and toured under the unwieldy name Anderson-Bruford-Wakeman-Howe.
True story.
