Where Do The Boys Go is another single by Men Without Hats that I remember though it was not a hit.
Did Alphaville (not sure of the spelling) have any hits stateside. Big In Japan was the smash over here. They are mentioned in the back of The Crack In The Cosmic egg as being a German band of absolutely no interest to those into Kraut Rock.
Another Alphaville song was Forever Young which kind of pre-dated the Nordic cool synth pop of Aha.
