“Imagine the best person in the world.

Now imagine that person being your dad.

I’m so grateful he was mine.

I’m so grateful I got to love him.

I’m so grateful I made it in time to hold him and say goodbye.

I love you forever Daddy.”

“Darling John Reilly,” Hughes wrote via Instagram while lamenting the loss.

Boy was he true to his word.

His dressing room was two doors from mine.

She added, “John’s sensitivity and kindness was most apparent with his family and friends.

His love of his wife Liz and their gorgeous daughters was legion.

I am so happy I got to experience and see that love firsthand.

One of a kind.

Fellow Irishman, God speed.
