Klaatu was a Canadian rock group formed in 1973 by the duo of John Woloschuk and Dee Long. They named themselves after the extraterrestrial Klaatu portrayed by Michael Rennie in the film The Day the Earth Stood Still. After recording two non-charting singles, drummer Terry Draper was added to the line-up; this trio would comprise Klaatu throughout the rest of the band's recording career. In Canada, the band is remembered for several hits, including "California Jam" (1974), "Calling Occupants of Interplanetary Craft" (1977) and "Knee Deep In Love" (1980). In the U.S. "Calling Occupants" b/w "Sub-Rosa Subway" was a minor double-sided hit and their only chart entry, peaking at No. 62 in 1977. The band is also remembered internationally for rumors that they were the Beatles recording under a pseudonym. Klaatu themselves did not start these rumors and always flatly denied them, and indeed no Beatle was ever involved in the writing, recording or production of any Klaatu material.
