After celebrating a total of ten Tony nominations—the most of any show this season—including one for Best Musical, the cast of A Gentleman’s Guide to Love & Murder brought a killer performance to Rockefeller Plaza as part of The Today's Show's "Best of Broadway" series on May 7. Bryce Pinkham and Lauren Worsham, who both received nods for their roles in the tuner, performed along with Lisa O'Hare the hilarious “I’ve Decided to Marry You.” Think Three’s Company with English accents. Check out the number below, then catch the musical romp at the Walter Kerr Theatre.
