Studying the dramatic arts under Lindsay Kemp, from avant-garde theatre and mime to commedia dell'arte, Bowie became immersed in the creation of personae to present to the world. Satirising life in a British prison, the Bowie composition "Over the Wall We Go" became a 1967 single for Oscar; another Bowie song, "Silly Boy Blue", was released by Billy Fury the following year. Playing acoustic guitar, Hermione Farthingale formed a group with Bowie and guitarist John Hutchinson named Feathers; between September 1968 and early 1969 the trio gave a small number of concerts combining folk, Merseybeat, poetry, and mime.
