"Unfortunately, Michael McDonald has come down with a viral infection while on tour that has impacted his singing," the DBG says in a release announcing the cancellation. "Despite his best efforts to push through, he regretfully has to cancel his show at the Denver Botanic Gardens tonight. Michael hopes to be able to reschedule the performance as soon as possible," the spokesperson added.
The Gardens closed at 3 p.m. today to set up for the concert.
