Matt Finish were a popular live band, which had a top 20 hit on the Kent Music Report singles chart with "Short Note" (1981).

[1] In his teens Moffitt formed a Blue Mountains-based band, Rum Jungle, which performed cover versions of rock musicians; their "gigs sometimes turned into bloodbaths.

His musical influences included NYC-based blues, soul and jazz groups; the Australian rock of Billy Thorpe and the Aztecs; and work by the Beatles and Led Zeppelin; and one of his inspirations was Jack Bruce's "Rope Ladder to the Moon".

[1] By 1977 the line-up of Rum Jungle included James Black (ex-Tymepiece) on guitar, Phil Colson, Mark McDonald, Bruce Sandell and Joe Sudouskas.

[2] In late 1978 and early 1979 at The Observer Hotel in The Rocks, Sydney, Moffitt played in a short-term funk band, Matt Finnish, with Brian Alcorn on bass guitar and Tony Georgeson on drums.

In mid 1979 Moffitt and multi-instrumentalist John Prior formed Matt Finish as a rock group with Brian Alcorn on bass guitar.

[2][3] Clayton rejoined by mid-1980 and the group issued their debut single, "Mancini Shuffle" in November via Peter Dawkins' label, Giant Records.

"[7] Matt Finish had developed a reputation for high-quality song writing and passionate, high energy performances, including national tours supporting U2, Midnight Oil, INXS, Ramones, Split Enz, XTC, Cold Chisel, Bryan Ferry and the B-52's.

According to Australian musicologist, Ian McFarlane, "[they] played a melodic brand of guitar-based pub-rock that garnered critical acclaim and a wide fan base.

In 1990 Moffitt returned to Sydney and formed a band, Blue Max, with Barrett on guitar and vocals, Christian Dunha, Bill Heckenberg on drums, and Glen Muirhead.

In June 1992 the group were signed to Mushroom Records and released a single, "One Day at a Time", in that month, which was produced by Peter Blyton (The Radiators, Machinations).
