The Kasenetz-Katz Singing Orchestral Circus was a bubblegum "supergroup" created by record producers Jerry Kasenetz and Jeffry Katz, consisting of various Super K Production groups. Probably the most cars ever on a album cover that weren't in a parking lot or aerial photo

For the first album, the fictitious concept was to take eight Kasenetz-Katz produced groups and bring them together for a "live" performance at Carnegie Hall on 7 June 1968. The roster included:

1910 Fruitgum Company
Ohio Express
Music Explosion
Lt. Garcia's Magic Music Box
Teri Nelson Group
1989 Musical Marching Zoo
J.C.W. Rat Finks
St. Louis Invisible Marching Band

According to the inner gatefold cover's liner notes, the "supergroup" consisted of 46 members.

Kasenetz-Katz came along and coined the term "Bubblegum", Their production company "Super K Productions" was a New York "bubblegum" hit factory, where a seemingly unending array of unusual sounding alias' were used in production so it wouldn't appear as the same group. In this manner Kasenetz-Katz managed to pull off a string of Top-40 hits in just under two years.

The generic 'Bubblegum" groups were manufactured in studios, some like "The Monkees" & "The Banana Splits" were made solely for TV. They prolifically recording lightweight, fluffy pop songs, mostly one-hit wonders and were often given quirky names. Below I've listed some of the groups that rolled off the "Super K Productions" conveyer belt.
