'Happy Hawaii' is a cover version of an Abba song. It was released in 1980 on a 7" single that was sponsored by Hapag-Lloyd Flug, an airline that operated between 1973 and 2007. It operated scheduled and charter passenger flights mainly to holiday resorts in Europe. Its successor is today's TUI fly Deutschland.
This single actually features two songs about exotic islands: the B-side is called 'Gran Canaria', which was released as a single in 1978.
