The Adventures of Kaptain Kopter & Commander Cassidy in Potato Land

The Adventures of Kaptain Kopter & Commander Cassidy in Potato Land was originally recorded by Randy California and Ed Cassidy during the 1972/73 hiatus period of Spirit. A concept album of sorts, interspersed with dialogue, its original scheduled release in May 1973 was cancelled by Epic Records. It was eventually released in an abridged form in 1981, with the first half as new recordings and the second comprising original recordings remixed with overdubs. A reworked and fuller version, still somewhat erroneously credited to Spirit, was released in 2006 and remains available as The Original Potato Land.
