Neeley, who played Jesus in the film, reveals many of his castmates have not been in a room together since the film wrapped.

He tells WENN, "I've seen all but two of them individually over the years but I haven't been connected with Larry Marshall, who played Simon, or Bob Bingham, who played Caiaphas. I've been trying to get this reunion to happen since the film came out.

"Carl (Anderson), who played Judas, and I did a lot of things together before and after the film and Yvonne, who played Mary, was with us once. I've been trying to get all of us together to do another production; if nothing else just to hang out for a few days. It's never happened until now, and the fact that we'll all be in the same place at the same time with (director) Norman Jewison is a miracle."

And it will be a big family affair for Neeley, because his wife, Leeyan Granger, will also be there. Granger and Neely fell in love on the set of the 1973 movie.

He recalls, "We were filming in this cave (in the Israeli desert) that was at least 60 or 70 feet from the surface of the earth down below... Norman was using existing light through the shaft where myself and Yvonne Elliman sat on this little rise. So the dancers are coming in doing their choreography with these big bowls of food sitting around this campfire. Yvonne and I are waiting for our cue to sing and we could see the dancers, who had long hair, would be very close to the fire.

"When Norman yelled 'Cut' I got up to walk over to these two ladies who had really long hair to say, 'Please just be careful'. Well, I tried to tell one of those ladies just that and I was rendered speechless! And this woman became my wife and she's still putting up with me almost 42 years later! My wife, our daughter Tessa and our son Zacharia will all be at the special screening on Monday."
