Andy Jowitt writes:  My sister-in-law is learning the harp and her teacher is a wonderful harpist called Lucy Bunce, who is ‘Director of Contemporary Music’ at St Andrew’s Church, Cherry Hinton, Cambridge and also offers a music ministry as part of the chaplaincy at Addenbrookes Hospital.  She has written a song of blessing for the NHS.  It’s due to be featured, together with an interview, on the Palm Sunday (28 March) edition of the BBC’s Songs of Praise.  Do look out for it, and I hope you’ll enjoy it.
