Vocal harmony group Purest Form was discovered when the manager of Rainbow’s End saw them busking in downtown Auckland. Their smooth harmonies were used to promote the amusement park — “take me back to the rainbow, that rainbow kinda magic!” — in a 1993 commercial. Before splitting in 1997, they got four singles in the Kiwi top 40. Their cover of ‘Message to My Girl’ peaked at number two, and won Single of the Year at the 1995 NZ Music Awards; Purest Form was also nominated for Most Promising Group.
