premise: Tadpoles is the third album by the Bonzo Dog Band. It is largely a compilation of their work from the television show "Do Not Adjust Your Set", on which they were the house band. The US version of the album had a track list slightly different from that of the UK version: the US version removed "I'm the Urban Spaceman" and added "Readymades" the B-side of their follow-up single "Mr. Apollo".
hypothesis: Bonzo Dog Band's second album was released two years before Tadpoles.
reason: The context makes no mention of the second album, or when these were released. Therefore, the system has no way of knowing for sure.
