There were 3 of us there as well as 2 medical people and a social worker. The 3 friends all spoke to him as they injected the anesthetic to make him sleep, before the other drugs. So the last thing he heard was voices of friends. They also played some soft classical music in the background, which Dennis would have liked. Solemn and sad but giving some power back to him, allowing him to make his own choice and die with dignity.
