Hard rock,heavy metal, ska, psychedelic rock and proto-punk were emerging. This party tune has been described by Stewart Copeland of the Police as a brilliant example of early "white reggae". It has lyrics that are kinda kooky and there's a lot of gonzo background singsong nonsence, too. A playful ditty that critics shouldn't take too seriously. It's just plain fun. This tune's title has various other spellings such as "obladi oblada". It has a simple cheerful free-for-all air to it that today's corporate disposable entertainment business doesn't allow.

Nothing to get hung up about, but it's not the same as saying "shit happens". .

A simplified way of saying, "Life goes on". The phrase first came to be in the popular beatles song by the same name, and since then, has became an extremely common phrase in pop and youth culture.
