Just learned from a friend that Ciambotti has died in Los Angeles. Clover, originally from Marin County, was the backing band on Elvis Costello's debut album My Aim Is True, save for harmonica player Hugh Cregg (later Huey Lewis), who didn't perform on MAIT. Ciambotti later became a doctor of chiropractic and practiced in the LA area.
Here's a video of Ciambotti performing with Costello and Clover at a benefit several years ago at the Great American Music Hall.
