A third engagement, a benefit concert for a foundation in India scheduled for February, will be postponed until Mehta is well enough to conduct. Austrian conductor Manfred Honeck, the music director of the Pittsburgh Symphony Orchestra, will conduct the waltzes. German conductor Cornelius Meister, artistic director of the ORF Vienna Radio Symphony Orchestra, will take over "Die Fledermaus."
The 81-year-old Mehta plans to retire next fall from his position as music director of the Israel Philharmonic Orchestra.
