The group was formed in San Francisco in 1967 when Johnny Ciambotti joined up with John McFee, Alex Call and Mitch Howie who were members of a group called the Tiny Hearing Aid Company. Clover's first gig was July 4 1967.
They performed around the Bay Area over the next two years eventually signing with Fantasy in 1969. They recorded two albums and one single for Fantasy in the early 1970's. Eventually an expanded line-up of the group moved to the UK in 1975 or early 1976. There they released two further albums, and (uncredited) backed Elvis Costello on his debut album My Aim Is True (1977). The group broke up in 1978 after returning to the US.
The group is most well known outside the US for their version of Route '66 in the Levis Jeans commercial.
Around 1976, Huey Lewis joined this band (credited as Huey Louis) and appeared on the two final Clover albums released 1977.
