This week's webcast, taken from last term, includes music by John Stainer and Kenneth Leighton.
Leighton's Second Service was composed in 1970 in memory of Brian Runnett, Organ Scholar at St John's between 1960 and 1963.
Locus Iste is the 100th recording by the Choir of St. John's College, Cambridge and marks the 150th anniversary of the consecration of St John's College Chapel.
The Choir of St John’s continues its commitment to new music by premiering a new cycle of works by Composer In Residence Michael Finnissy.
