The casts of Family Guy and It's Always Sunny in Philadelphia present this week's longest title, It's Always Sunny In Philadelphia — Live On Stage/Family Guy — Live: A Special Benefit for Haiti/Partners in Health. The Sunny gang will perform their mock-opera “The Nightman Cometh.” Danny DeVito, who plays Frank, tells us he loves the energy of playing live. “The rowdier the better,” he replied to a publicist-chaperoned interview by e-mail. His big number is the rollicking “Troll Toll,” though he describes his singing voice by saying, “I'm somewhere between Enrico Caruso and Arnold Stang.” How is he preparing for this huge venue? “I'm gonna put a sock in my pants.” And this just in: Sarah Silverman and Jeff Ross have been added to the bill to make the title even longer, not to mention more politically incorrect.
