Kate and her husband Miles both came to the Christian faith initially through music – Kate through a gospel choir in London’s Notting Hill, and Miles while singing as a choirboy in an Anglican church. Kate began writing songs the day after she became a Christian, often co-writing with pianist/producer Mark Edwards. They formed an evangelistic band called The Fabulous Sister Brothers, known for its gospel message and the artistry of its stellar musicians.

Miles and Kate met and married while both attending Church of Christ the King in Brighton, England (now known as Emmanuel). After visiting the Brownsville Revival in Pensacola, Florida, Kate began to lead worship, with a door opening to immediately minister at significant gatherings such at the Stoneleigh Bible Weeks, the Newfrontiers International Leadership Conferences, Spring Harvest, Mission Worship and many other events in the UK, Europe, Canada and the USA.

During this time Kate released three solo albums: ‘One Day’, ‘Heart & Soul’ and ‘Redemption Songs’. Later releases include ‘The Grace EP’ produced and arranged by UK band PHATFISH, and ‘Christmas’, a co-release with Geraldine Latty and Carey Luce. Kate’s songs have appeared on over 50 worship albums to date.

In 2007, Kate and her husband Miles felt God leading them to move from the UK to Sydney to build into local worship ministry, inputting into teams and training worship leaders. Kate has developed a Worship Leader Training Course and has the joy of mentoring many people into this ministry.

Music in the Simmonds' home is very much a family affair. Miles and Kate have been married and ministering together in worship for the last 28 years. Their son, Matt, is a gifted multi-instrumentalist and they often lead worship together as a family. Inspired by the CityAlight ethos of crafting songs with Biblically-rich lyrics and strong, simple melodies, they now have the joy of growing together in writing and recording congregational worship songs that can serve churches of all sizes.
