Although he sang in a skiffle group while in secondary school, Rendall originally had no intention to sing opera professionally. He was "discovered" while working at the BBC, sorting records for Desert Island Discs. A producer for the show heard him singing "Questa o quella" from Rigoletto while working, and suggested he study professionally.[1]
Rendall entered the Royal Academy of Music in 1970, and the Salzburg Mozarteum in 1973. He won a Young Musician of the Year Award from the Greater London Arts Association in 1973 and received a Gulbenkian Fellowship in 1975. In May 1978 he sang the tenor part of Anton Bruckner's Te Deum under the baton of Herbert von Karajan during a performance at Musikverein Hall of Vienna with Vienna Philharmonic.
Rendall was involved in a peculiar onstage incident in 1998 when he accidentally stabbed baritone Kimm Julian in the death scene of I Pagliacci during a rehearsal with the Florentine Opera. The switchblade-style knife that the Milwaukee opera company used failed to collapse, and the baritone received a 3-inch-deep (76 mm) cut into his abdomen.[9][10][11][12] Julian recovered and police cleared Rendall of any wrongdoing.[13] He suffered injuries from a collapsing stage set during an April 2005 performance on stage in Copenhagen, and his career was subsequently curtailed.[14] Rendall returned to performance in June 2013.[15]
