Editing Alfred Deller (section)

===Collaborations===
In 1960, Deller sang the role of Oberon in the first production of [[Benjamin Britten]]'s opera ''[[A Midsummer Night's Dream (opera)|A Midsummer Night's Dream]]''.<ref name="kentnews-22jun2012"/> Britten wrote this role with Deller specifically in mind, although he was dropped from staged revivals of the work against the composer's wishes, largely because of poor acting technique. The smallness of his voice was also a negative factor in the casting process at Covent Garden.<ref name="Steane"/> He did record the opera, with the composer conducting in 1967. The 1960 premiere, broadcast by the BBC, is now commercially available and finds Deller in fresher voice; [[Myfanwy Piper]] described his singing of Oberon as "unearthly".

Lutenist [[Desmond Dupré]] performed with him, initially as a guitarist; other accompanists included harpsichordist and musicologist [[Walter Bergmann (musician)|Walter Bergmann]]. In later years, he worked with lutenist [[Robert Spencer (lutenist)|Robert Spencer]] and harpsichordists [[Harold Lester (musician)|Harold Lester]] and [[William Christie (musician)|William Christie]]. His recordings include the lute songs of Dowland, operas by Handel, Britten's ''A Midsummer Night's Dream'', songs and semioperas by Purcell (such as ''[[The Fairy-Queen|The Fairy Queen]]''), traditional English folk songs, works by [[Thomas Tallis]], and the Bach alto repertoire. He recorded for [[His Master's Voice (British record label)|His Master's Voice]], [[Vanguard Records|Vanguard]] Classics, and [[Harmonia Mundi]].

Deller also sang [[John Blow]] and Henry Purcell Odes like "Sound the trumpet" from [[Come Ye Sons of Art]] with the other great counter-tenor of the day, [[John Anthony Whitworth|John Whitworth]] (1921–2013), who is favoured by critic Richard Lawrence for his magnificent voice.<ref>[https://www.gramophone.co.uk/classical-music-news/obituary-john-whitworth-countertenor Charlotte Smith: ''Obituary: John Whitworth, countertenor''.] Gramophone, 5th Sep 2013</ref>
