If you watched the King’s Coronation Concert, the Queen’s Platinum Jubilee music extravaganza, or were one of the millions tuned in to Prince Harry’s wedding, you’ll have heard some of choir director Mark De-Lisser’s arrangements.

Mark puts bespoke choirs together for major events, liaising with artists like Lionel Ritchie, Alicia Keys, Katie Perry and Andrea Bocelli. But he tells Helen it took years to discover his purpose in life after a series of failures in the wrong direction.

Mark gets the nation singing; leads Vicky McClure’s Dementia Choir; features in shows like Songs of Praise and The Masked Singer and is about to embark on quantifiable research to discover how singing affects our bodies and brains.
