Bangor Flying Circus was a progressive rock trio from Chicago, USA, formed in mid-1967. It consisted of David "Hawk" Wolinski (bass, keyboards, vocals), Alan De Carlo (guitar, vocals), and Tom Schiffour (drums), who was replaced in late 1968 by former H.P. Lovecraft member Michael Tegza (drums, percussion). Wolinski and Schiffour had previously been in the Shadows of Knight. They put out one self-titled album in 1969. After they brokeup Wolinski and DeCarlo formed Madura.
