スーパースター・ビリー・グラハム
Hart trained the vast majority of his trainees in the basement of the Hart mansion, known as The Dungeon. Hart used the location from the time that he bought it in October 1951 until the late 1990s. All eight of his sons and many others such as Junkyard Dog, Jushin Liger, Superstar Billy Graham and The British Bulldog were educated there.
