According to an interview with Mulligan, he headlined the first wrestling event at the new Madison Square Garden against Sammartino in 1969.

In an interview with a wrestling website before his death, Mulligan said that despite some strife along the way, he had led a "blessed" life.

"Life has really been super to me...I've had such a blessed life. God blessed me...I mean, I was a little kind from a west Texas town...and got every dream that he ever wanted. I mean...it's amazing. Even my life today...there are some super highs and some lows—but even to this day, I'm very blessed."

Mulligan was 73 years old.
