Originally scheduled for Dec. 12, the performance will now take place at the famed venue April 29, 2015, at 8 PM. The postponement is due to "an unanticipated scheduling change related to a film project."

At Carnegie Hall, McDonald will be joined by music director and pianist Andy Einhorn, bassist Mark Vanderpoel and drummer Gene Lewin.

All tickets to the Dec. 12 concert will be honored on April 29. For further information, ticketholders may contact CarnegieCharge at (212) 247-7800.

The Carnegie Hall performance is part of a 26-city concert tour that will kick off Dec. 2 at Los Angeles' Walt Disney Concert Hall and will continue through May 9, 2015, at the Tilles Center for the Performing Arts in Greenvale, NY.
