iSingPOP is a primary school music project that brings together school, church and community. Thousands of children will be given the opportunity to record their very own album and perform a live concert in the local church -

We write and produce songs that are used face-to-face, in schools and with families and church groups. Fischy songs such as ‘Build Up’ and ‘You are a star’ are part of the everyday lives of children, schools and families across the UK and beyond.
