Where did their name come from?? does it mean something in norwegian or wherever they came from?

The origin of the name "a-ha" comes from the lyrics of an early song ("Nothing To It"). After checking dictionaries in several languages, they found out that "a-ha" was an international way of expressing recognition, with positive connotations. It was short, easy to say and unusual.
