made with only piano accompaniment, added a studio orchestra, and reissued the recordings. A foreshadow of overdubbing can be seen with Sidney Bechet, an American jazz musician who made a pair of famous overdubbed sides in 1941 entitled "The Sheik of Araby" and "Blues of Bechet". The multi-instrumentalist recorded the clarinet, soprano, tenor saxophone, piano and the bass and drum parts for both songs, and then he recorded each track separately on top of one another to create two single tracks. The recordings were then issued as "Sidney Bechet's One Man Band". The 1946 Disney animated film Make Mine Music includes overdubbed duo and trio performances by Nelson Eddy as an opera singing whale. The 1950 Disney film Cinderella used multiple tracks for vocals for the song "Oh, Sing Sweet Nightingale". In 1948, experiments mixing sound effects and musical instruments made by Pierre Schaeffer at the Radio Télédiffusion Française experimental studio in Paris led to Étude aux Tourniquets, the first avant-garde composition using recording as a composition technique, recorded, and mixed directly on acetate records as tape recorders were not yet available. Similar sound collage experiments had been made by Edgard Varèse in the 1920s, but Varèse, also a French composer, wrote scores later played live by musicians. As from 1949, Schaeffer composed and recorded on acetates with Pierre Henry (Symphonie pour un homme seul, 1950), who also recorded with Varèse in 1954. Together, they used some of the earliest tape recorders available in the early 1950s. The invention of magnetic tape opened up new possibilities for overdubbing, particularly with the development of multitrack recording with sel-sync. One of the first known commercially released overdubbed recordings was "Confess" for Mercury Records by Patti Page in 1948, although this overdubbing was done with acetate. With the popularity of this recording, Page recorded "With My Eyes Wide Open I'm Dreaming" using the same overdubbing technique. The vocals were listed as "Voices by: Patti Page, Patti Page, Patti Page, Patti Page". Les Paul was an early innovator of overdubbing, and began to experiment with it around 1930. He originally created multi-track recordings by using a modified disk lathe to record several generations of sound on a single disk, before later using tape technology, having been given one of the first Ampex 300 series tape recorders as a gift from Bing Crosby. His 1950 #1 hit, "How High The Moon", performed with his then-wife
