Life's Never Been So Good is a song from the environmental children's musical One Sun One World, by Peter Rose and Anne Conlon.

One Sun One World was written in partnership with WWF to commemorate the 50th anniversary of WWF-UK. The first performance was at London's Royal Albert Hall in 2009.

"I can think of few better ways of alerting children to the problems of global ecological concerns than by introducing them to the musicals of Peter Rose and Anne Conlon" - Sir David Attenborough
