They achieved considerable local success in the late 1960s, with ten of their fourteen singles reaching the New Zealand Top 20.
The Fourmyula's best known song, "Nature", written by Wayne Mason and produced by Peter Dawkins, reached number one in the New Zealand charts in December 1969.
The Mutton Birds released a rockier version of "Nature" in 1995, and in 2001 the original version was voted New Zealand's greatest pop song ever - becoming the title track of the best-selling Nature's Best compilation.
In 2010 the band reformed to promote the compilation The Complete Fourmyula, a 4-CD set which includes a previously unreleased album Turn Your Back on the Wind, originally recorded for Decca.
