The Sinfonietta is entitled 'Symphonic Phantasy' on the unpublished manuscript (echoes of the original title of Sibelius's Seventh Symphony) and it remained unperformed during the composer's lifetime. He was unsure of it and told the conductor Christopher Whelen, to whom he gave the manuscript in 1950, that he didn't want it played. Whelen faithfully obeyed this injunction until 1983, when he was very reluctantly persuaded to let it be performed during Bax's centenary year. (He had previously refused a request from Robert Ponsonby to allow it to be premièred at a Prom in 1980, where it would have shared the program with the first performance of Rubbra's Eleventh Symphony under Nicholas Cleobury.) Vernon Handley and the BBC Welsh Orchestra eventually gave the first performance at a recording session in Llandaff on 25 June 1983 for broadcasting later that year. (Odd to think that it has only ever been played in Wales and Czechoslovakia.)
