Bob, New Jersey has enacted a statute to prevent bands from playing here if the band has no original members and does not have a legal right to use the band name. It's characterized as consumer protection (i.e., to prevent people from getting duped by paying good money to see a phony band). I believe that the impetus for this was some of the stuff done with touring bands using the names of well-known bands like the Drifters and Platters.
