On the Huey Lewis & the News' Facebook page, the bad news about Lewis' illness was broken:
To our fans in Orlando. We are so sorry we have had to cancel our appearance at SeaWorld this coming weekend. We were looking forward to seeing you there, but Huey is unwell, and under doctor's orders he cannot perform. We are sorry to disappoint our fans, and will try to reschedule as soon as possible.
SeaWorld has replaced Lewis with southern rockers Alabama on Saturday, Chris Young plays the Sunday slot. And the following weekend sees Hanson and Daughtry.
