Kushnier isn't the only member of the show's cast to find performing on the Strip a new experience. "Every night's an adventure when there are cup holders in the seats," laughs Erich Bergen, who plays Four Seasons co-founder Bob Gaudio.
The biggest adventure of them all was the show's official opening night last month, which included a huge party where an enormous projection surface dropped away to reveal two-dozen go-go dancers. The performance was held on the 74th birthday of the group's lead singer Frankie Valli, and it allowed the chance for the Boys cast -- including Rick Faugno who plays Valli, and Jeff Leibow, who plays Nick Massi -- to meet some of the show's real-life counterparts. "The party was pretty impressive," says Leibow, "but bowing with those guys was really amazing."
