There is more than one artist with this name: 1) Oberon is an Oxfordshire early 70s progressive-psychedelic-folk-rock band. They played a mega-rare privately pressed album named "a midsummer night's dream" in 1971. Only 150 copies were pressed making it one of the most obscure folk albums of the era. Acorn was a very small local label who also issued the first album by The Yetties. After a reissue in 2005 their album became quite popular between folk-rock fans.
