Rockers Heart cancelled a concert in Utah on Wednesday (03Apr13) to allow singer Ann Wilson to recover from a bad cold.
The band was due to perform in Ivins, but the show was postponed at the last minute due to the star's illness.
Wilson hopes to be well enough to perform as planned in Henderson, Nevada on Friday (05Apr13).
A post on the group's website reads, "For just the second time in more than ten years, Heart has had to reschedule a show. Lead singer, Ann Wilson, returned from Heart's Canadian tour with a bad cold that affected her voice.
"She is expected to recover in time to perform in Henderson Nevada on April 5. Information on the rescheduled Ivins, Ut show will be posted on heart-music.com as soon as it becomes available."
