Country star Keith Urban is canceling appearances and must postpone an upcoming benefit concert after scheduling throat surgery for a polyp that has developed on his vocal cords. "All for the Hall," a benefit for the Country Music Hall of Fame and Museum scheduled for January 18th, will need to be rescheduled while the singer recuperates. The concert, with Urban hosting, was set to feature Vince Gill, Allison Krauss, Rascal Flatts and others.
Urban, who is married to Nicole Kidman, recently notched his 13th Number One single on the country charts with "Long Hot Summer." Until his surgery – an outpatient procedure described as "minor" – he will honor a few upcoming appearances that require him to sing just one song. The New Zealand native will reschedule all other dates.
