Klaatu was a Canadian band that their record company(Capitol), held their identity a secret because they had a few songs that sounded suspiciously like the Beatles...Dr. Marvello Sub Rosa Subway and, especially Calling Ocupants had some very conincidental stylings to the Fab Four...Created a big hub bun at the time..Good stuff...I think they may have had a couple more albums after the initial one, but I'm not familiar with those...
