Ray White had been slated to perform three dates this weekend in Denver with Steve Kimock, Bobby Vega, Melvin Seals and John Molo. However, Kimock and Vega’s former bandmate in KVHW (with Alan Hertz) has dropped off the bill. Stepping in on vocals, however, will be Joan Osborne. She will fill out the group, which will appear at Owsley’s Golden Road on April 25-27, with Underground Orchestra opening the first two nights.
