Extensive acoustic testing took place in 1964 with local schools taking part clapping, shouting and reacting to loud, off-stage bangs. The first performances took place on 22–23 January 1965. The first half of the programme was a classical concert given by The Arriaga String Quartet and the second half was a performance of Benjamin Britten's Noye's Fludde with 14 local schools participating. The soloists were Sheila Rex and Owen Brannigan. Britten himself attended one of the dress rehearsals.^[2]
