The band was formed as a quartet by songwriter and former Hallé Orchestra percussionist Richard Witts in 1978, but later became a trio.

Witts produced the band's recordings and sang on most of their releases, the occasional lead vocal being taken by Tony Friel or Andy Wilson.

"XOYO" also appeared on the Cherry Red compilation album Pillows & Prayers.

Andy Wilson is a club and radio DJ based mainly in Ibiza.

In 2003, the entire Passage back catalogue was reissued and remastered across 5 CDs by the LTM label.
