Singers have their favorite songs. So do composers, and the songs they're partial too aren't necessarily ones they wrote themselves! This month, we talked with Marcy Heisler and Zina Goldrich, Marcus Hummon, Ben Moore, Laurence O'Keefe, Anthony Rapp, Alice Ripley, Victoria Shaw, and Lari White about their favorites. Plus, we caught Ripley singing Jason Robert Brown's popular tune "I Will Follow," and Shaw -- accompanied by White and Chuck Cannon -- singing her composition "The River" as part of the Broadway at Birdland series.
