Rock ’n’ roll fans have long preferred their musical idols to have a touch of the bad boy in them, if not an actual rap sheet. Of course, they also had to have the pipes to go along with the felony charges, and that’s how the Four Seasons made their mark back in the day. Once again, those bad-boy Jersey Boys are at Playhouse Square to rock AARP members out of their seats while showing young folks how vocal groups in the ’60s made the magic happen. From the start, we watch as the group struggles to assemble its talent, with key members continually passing in and out of Rahway State Prison. But eventually they trade their B&E’s for harmonies, and the legendary foursome is on its way. Jersey Boys opens tonight at 8 at the State Theatre and runs through May 18. Tickets are $30 to $110.
