Trevor George Lucas (25 December 1943 – 4 February 1989) was an Australian folk singer, a member of Fairport Convention and one of the founders of Fotheringay.

He had a deep, rich pleasant voice, which he adapted well to blues, work-songs, shanties and bush ballads, shifting his accent around from 'black' American to 'Outback Oz', without ever sounding like anybody but himself.

[7] By May 1969 Lucas was dating Sandy Denny, lead singer of Fairport Convention, when he played triangle in Si Tu Dois Partir on their album Unhalfbricking (July 1969).

[9][10] Allmusic's Dave Thompson was not impressed by Lucas' vocals, "great guitarist though he was, his voice offers nothing that you could not hear in any amateur folk club, any night of the week, rendering Dylan's 'Too Much of Nothing', Gordon Lightfoot's 'The Way I Feel', and his own 'Ballad of Ned Kelly' little more than makeweights".

[11] Whereas Nick Talevski in Knocking on Heaven's Door: Rock Obituaries (2006), found "The Ballad of Ned Kelly" to be a highlight of the album.

In 1972, Lucas organised and produced a one-off album, Rock On by "The Bunch," which featured 12 classic oldies favourites performed by past and (then) present members of Fairport Convention, as well other friends.

He became a session musician and record producer for Bronco, Julie Covington, Al Stewart, The Strawbs and Richard & Linda Thompson.

[2][5] During July and August 1972 Lucas helped Fairport Convention record their album Rosie (February 1973) and brought Jerry Donahue in for several tracks.

In the mid-1970s the couple relocated to the village of Byfield in Northamptonshire, in July 1977 Denny gave birth to their only child, a daughter, Georgia Rose Lucas.

[16] Linda Thompson told The Guardian that shortly after the birth of their daughter Georgia in July 1977, Denny "was crashing the car and leaving the baby in the pub and all sorts of stuff.

[17] In late March 1978, while on holiday with her parents and baby Georgia in Cornwall, Denny was injured when she fell down a staircase and hit her head on concrete.

[18] Following the incident, she suffered from intense headaches; a doctor prescribed her the painkiller Distalgesic,[17] a drug known to have fatal side effects when mixed with alcohol.

[17] On 13 April, concerned with his wife's erratic behaviour and fearing for his daughter's safety, Trevor Lucas left the UK and returned to his native Australia with their child.

[24][25] Back in Australia Lucas produced Wayne Gillespie's New Locations album for CBS NZ at Byron Bay's Music Farm (January 1986), co-composed film soundtracks with Ian Mason including for Jenny Kissed Me (1986) and Slate Wyn and Me (1987).

[5] For the 1986 horror-thriller feature film, Cassandra, which Lucas produced, he and Mason composed the score and the song, "Land of the Free" and performed it as Bluey and Curly.
