It's just too good to be true! The cast and creators of Jersey Boys, which opened at the August Wilson Theatre on November 6, 2005, celebrated its eighth Broadway birthday on November 10. The show follows the rise of Frankie Valli and the Four Seasons, the popular 1960s pop/rock quartet made famous by hit songs such as "Walk Like a Man" and "Big Girls Don't Cry." After Sunday's show, headliners Dominic Scaglione Jr., Matt Bogart and other company members (including co-librettist Rick Elice and original Four Season Bob Gaudio) headed to Novotel for a gigantic cake.
