Knight's classical roots were well hidden until he recorded "A Canon by Telemann" on the album Back In Line, multi-tracking with himself on this tricky baroque piece. In the mid-70s he was once secretly a member of The Wombles and appeared on Top of The Pops as Uncle Bulgaria, with Rick Kemp and Bob Johnson also in Womble suits.^[1] He left Steeleye Span in January 1977, when it started to look as if the band was about to break up. Knight teamed up with Johnson again to record a concept album The King of Elfland's Daughter (1978), based on the novel by Lord Dunsany. It included one song sung by blues legend Alexis Korner and another by Mary Hopkin. In 1980 he returned to Steeleye Span and appeared on every one of their albums since then up until Wintersmith (released October 2013).

He announced his decision to leave Steeleye Span at the end of 2013 on his website on 14 November 2013.^[2]

Some of the most accomplished folk fiddlers of England and Scotland joined together for a tour in 2001. An album of live performances from the 2001 tour was sold as "Feast of Fiddles" in 2002. The group has continued to tour annually since 2001, but describe themselves as "unsigned". They sell albums of live performances from previous concerts, but in a very restricted way. The CDs are available at the gigs or over the internet. They consist mainly of traditional English tunes, in varying combinations of solo, duo or band.

• In 1982 Knight joined "Moire Music" a free-jazz group led by Trevor Watts, while still remaining a member of Steeleye. Liam Genockey was drummer with the group, and would later become a member of Steeleye Span, when Nigel Pegrum left.
• Knight's classical and jazz influences surfaced again in 1998 when he recorded An Ancient Cause and The Gemini Cadenza, multi-tracking with himself.
• In 1995 he recorded an album with bass-player Danny Thompson,^[3] best known for his work with John Martyn.
• Knight is concentrating^[when?] on developing his trio Gigspanner which features himself on fiddle, Vincent Salzfaas on percussion and Roger Flack on electro-acoustic guitar. They play a blend of traditional folk and hot jazz with African rhythms. Their debut album, released in November 2008, is called Lipreading The Poet. It was named by The Wire magazine as one of the best 15 'Global' Albums of 2009. They are undertaking an increasing^[when?] number of touring and festival commitments.
• Knight formed Tanna with guitarist Kevin Dempsey and Tom Leary during the 2000s.^[4]
• He appeared as a guest on Mostly Autumn's 2007 album Heart Full of Sky and performed as a guest at their album launch show at the London Astoria on 10 February 2007.
