Singer Don Ho is in the hospital for observation after experiencing shortness of breath.
Ho, 75, was admitted Friday and was expected to stay a few days, his spokeswoman, Donna Jung, said Sunday.
Jung had no further information about the singer’s condition.
Ho will reschedule his shows at the Waikiki Beachcomer Hotel through the rest of the month.
A mainland concert tour set to begin next month will be postponed as well. He had been due to perform in Santa Fe, N.M., San Juan Capistrano, Calif., and at the University of Oklahoma in late September.
Ho celebrated his 75th birthday on Aug. 13.
