A number of shows must be rescheduled or canceled to allow medication to take effect and to prevent permanent damage to Lewis’ voice, according to his doctors.

The rescheduled shows are the November 5 and 6 performances at the Wiltern in Los Angeles and the November 8 concert at Memorial Auditorium in Sacramento.

The Los Angeles shows will be combined into one concert at November 13 at the larger Palladium where tickets for the Wiltern shows will be honored. The Sacramento show has been rescheduled for November 15.

Unfortunately, routing difficulties prevent the rescheduling of the band’s performances in San Jose, Calif. (November 9); Boise, Idaho (November 12); Salt Lake City (November 13); Fargo, N.D. (November 17); and Pittsburgh, Pa. (November 22).

Refunds for these shows are available at point of purchase.

The tour is set to resume Tuesday (November 11) in Spokane, Wash.
