CHEYENNE - A booking company for Cheyenne Frontier Days is suing an animal rights group in the wake of a decision by the Matchbox Twenty pop rock band to pull out of a scheduled performance this summer.

The lawsuit was filed in federal court in Cheyenne by Omaha, Neb.-based Romeo Entertainment Group.

It seeks a court order to stop the group called SHARK, which stands for Showing Animals Respect and Kindness, from contacting any entertainers that have agreed or may agree in the future to perform at Frontier Days.

The lawsuit contends SHARK was using inaccurate and misleading information in its effort to persuade entertainers to drop their performances in Cheyenne.
