"Ob-la-di ob-la-da" was a great hit and was on everybody's lips (and those of their dogs for that matter) at the end of 1968. The song has a nice happy feel about and for some reason it always makes me think of the Caribbean. The version that I play can be found in Beatles Songs for the Recorder
By the way, what does "Ob-la-di ob-la-da" actually mean? Is it a Beatles invention or an actual expression in a real living language?
