After working as a roadie for Brinsley Schwarz, in 1972 he formed Ducks Deluxe,[2] issuing two albums on RCA.

Belmont continued as an in-demand sideman across a wide spectrum of music, with sessions for Elvis Costello,[4] Billy Bragg, Carl Perkins, Jona Lewie, John Hiatt, Desmond Decker, Johnny Cash,[5] Eddie Grundy and others.

His first manager and old friend Dave Robinson then suggested he should invite former bandmates to provide vocals on his next recording, resulting in Belmont recording songs with Carrack, Nick Lowe, Carlene Carter, Graham Parker, Sean Tyla, Geraint Watkins, Hank Wangford, Johnny Nicky, Barbara Marsh and Reg Meuross.

Much of the album The Guest List was recorded at Goldtop Studio, with a 'house band' featuring Roy Dodds, Kevin Foster and Howard Hughes.

Currently, Belmont is playing in Los Pistoleros, The Johnny Nicky Band, Hank Wangford, My Darling Clementine and The Lost Cowboys and the newly reformed Ducks Deluxe.
