I saw Colm Wilkinson... Tim Shew a couple of times (he was alright)... I did not see Gary Morris. He was off that day.
Colm is the best Jean Valjean, but there was an actor from down-under who was a understudy... he was the 2nd best. Very physical, clear lovely tenor voice. I don't remember his name. It was in the late 80's - early 90's. But I could see him again.
