For most of its existence, the choir at King's drew its singing men ("lay clerks") from the Cambridge community, granting lifetime appointments. Reforms at the end of the 19th century gradually introduced undergraduates into the choir. The last lay clerk left the choir stalls in 1927, and today 14 members of the alto, tenor & bass sections are choral scholars, undergraduates (and occasionally graduates) studying a variety of subjects in the College itself. As part of King's College Choir, the choral scholars sing in the chapel's daily services, which remain the choir's raison d'etre, as well as maintaining a concert, recording and touring schedule. As Collegium Regale, the choral scholars perform independently of the choir, singing a repertoire that encompasses 15thC sacred music, jazz, folksongs and pop. "Coll Reg" provides entertainment at dinners, conferences, and Cambridge charity events. Coll Reg was in existence by 2002, as it was adjudged to be under the jurisdiction of the Use of Choir committee at that time.
