TSO’s annual November-December multi-sensory extravaganza, which sells out venues year after year, has cemented the group’s status as a must-attend, multi-generational, holiday tradition. This year’s 20th anniversary tour, a presentation of TSO’s unforgettable “The Ghosts of Christmas Eve,” featuring founder/composer/lyricist Paul O’Neill’s timeless story of a runaway who finds her way into a mysterious abandoned theater, will return to Smoothie King Center on December 19. Tickets go on sale Friday, September 14 at 10 am at Ticketmaster. TSO’s Winter Tour 2018 is presented by Hallmark Channel.
