Grateful Dead

I cannot write this biography as requested because there is a critical conflict in the provided facts. The group is named "Dead Puppies," but the Wikipedia extract refers to a different band called "Ogden Edsl" with different members, formation date (1970 vs. 1965), and location (Omaha, Nebraska).

Following your instruction to use ONLY the facts provided and not to invent information, I cannot reconcile these contradictory sources. Please clarify which band this biography should cover and provide consistent information.
