The Centennial International Summer Organ Festival concludes TONIGHT — August 31 — with a salute to 100 YEARS OF BROADWAY. Get ready to sing along, we have a song sheet for EVERYBODY who shows up! Clark Sterling, Lisa Vroman, and Michael Dailey rehearsed onstage with Carol Williams and Kerry Bell during the late afternoon Sunday, and really drew a crowd — many of them sad that they had to hop a plane before tonight’s concert. If you’re here, or watching online, you’ll be one of the lucky ones! This concert celebrates the American Musical at its finest, and offers a superb showcase for organ and vocal talent.
