Josh Groban is going back to school to celebrate the 25th anniversary of the arts institute from which he graduated in 1999.
The singer will join Barry Manilow, Natalie Cole, Placido Domingo and Janet Jackson, among others, who will be part of the Ahmanson Theatre celebrations when the Los Angeles County High School for the Arts turns 25 later this month.
Groban isn't the specialised school's only big success story - past students include actress Jenna Elfman and High School Musical star Corbin Bleu.
Manilow, a longtime supporter of the school, will be among the honourees at the gala.
