Prior to the establishment of the original stable male-only group cited above, several of the parts were taken by other singers, including three females. The four founding members, who first sang together within a six-man group in 1965, were Alastair Hume, Alastair Thompson, Simon Carrington and Brian Kay. From 1965 until 1968 the first countertenor was Martin Lane and the first baritone was Richard Salter. It was this group of six singers who gave the first concert under the name of the King's Singers on 1 May 1968 at the Queen Elizabeth Hall, London, with the Academy of St Martin-in-the-Fields, Simon Preston (organ) and Barry Tuckwell (horn). Later in 1968, Martin Lane developed a brain tumour and had to withdraw from the group; Felicity Palmer stood in during 1969 until Nigel Perrin graduated that summer. Then, in 1969, Richard Salter was awarded a Richard Tauber Scholarship and left for Vienna; Nigel Beavan filled the gap until Anthony Holt became available towards the end of the year. Other singers who served as short-term group members were Eleanor Capp, Caryl Newnham and, on one occasion, James Bowman, all of whom took the first countertenor (soprano) role in 1969 when Felicity Palmer was unavailable. For a brief time after he joined the King's Singers, Nigel Perrin also belonged to the Scholars; when double-booked, his King's Singers' duties were fulfilled by Richard Baker (note: not the familiar BBC broadcaster). Neil Jenkins sang tenor in the early pre-King's Singers group's first summer singing tour in 1965, and Peter Hall was another tenor used by the fledgling pre-King's Singers group.
