Singer-songwriter Howie Day has canceled his appearance Sunday night at Shank Hall, the club announced. Day, who had previously been slated to perform Thursday night, apparently has canceled his entire tour.

Whatever malady prompted Day to bypass his Milwaukee stop may be contagious. Shank Hall also announced cancellations for Minneapolis roots rocker GB Leighton (Feb. 4), Sean Morey (Feb. 5) and the Jack Ingram Acoustic Tour (Feb. 11).

Customers are asked to return tickets to the place of purchase for a refund.
