SAN DIEGO (CNS) - Singer Josh Groban, who was set to perform at San Diego State University's Viejas Arena next Tuesday, canceled Tuesday because of a scheduling conflict.

Groban, known for his wide vocal range, won't be able to book another San Diego appearance this year because of the way his tour is set up, according to a statement issued by Live Nation, which promotes concerts at most San Diego venues.

Refunds are available at the point of purchase.
