"I always wanted to do Dean but they said 'you have to mature into that role'. I felt closer to the character because of that silly, comic element," he said.
"I would watch him on TV, he was a grown man in a suit acting like a 12-year-old, I liked that he could put smiles on people's faces."
Edwards picked up a lot of Martin's personal traits through watching videos and later meeting original band members who knew the man himself.
"When I was in Palm Springs I became friendly with some of Martin's family and friends who gave me copies of home movies, to see what he was like behind the scenes.
"There's one where he was at a barbecue, he's just as easy going, he really didn't care that people looked at him like a star, he just wanted to enjoy what he did." The popular show continues to stand the test of time, capturing a little slice of history at the same time.
"These guys were famous before there was internet - they were just natural icons who had talent with minimal effort.
"It was a time when music had meaning, the songs were well written, it was also a time when there was prejudice, here was a black man and two Italians who behaved like brothers."
People could expect individual sets from all three artists, followed by a second half where they came together to sing duets.
The spotlight was also shared with crowd members, who will be a large part of the evening, Edwards says.
"We have a lot of people who sing along, but most importantly we encourage them to feel free to yell things out, it's got to be the only show where the audience becomes like a fifth cast member."
In 10 years working with The Rat Pack, their audience demographic had changed dramatically.
"With artists like Michael Buble drawing a younger generation, they want to see where those songs have originated. We have young guys who come dressed in suits and fedoras and we had a girl, of about 21, who is the biggest Dean Martin fan I have ever met - she knew everything about him and said it meant so much to be at our show.
"It's especially touching when you get the older people that come out, we have had people as old as 95-96, and we are taking them back to a time when they had a lot of fun."
All of the performers were selected for their individual talents and were dedicated to giving people a taste of what the real Rat Pack was like.
Tickets range from $50 to $55 plus service fees, available from Ticketek.
