Not long after the release of Electric Light Orchestra's first album, Wood found himself frequently at odds with co-leader Jeff Lynne. After increasing personal and musical differences it became clear that both could no longer work together in the same group, so Wood left, taking band members Bill Hunt (keyboards and french horn) and Hugh McDowell (cello), as well as ELO's sound engineer, Trevor Smith, with him, to form Wizzard. Also in the line-up were former Move bassist Rick Price, drummers Charlie Grima and Keith Smart (all formerly of Birmingham group Mongrel), and saxophone players Mike Burney and Nick Pentelow (the son of actor Arthur Pentelow). Prior to the recording of the band's second album, Introducing Eddy and the Falcons, McDowell left and was not replaced, and during the recording of the album Bill Hunt also departed and was replaced by Bob Brady (also from Mongrel). Prior to the recording of the band's final album, 2000's Main Street, in 1975, drummer Keith Smart departed the band and was not replaced.
