The band was formed late 1983 by Biff Harrison, Jim "Golden Boots" Chambers, Evil John Gieves Watson, Sam Spoons, Hugh Crozier and Dave Clennel.
They regularly performed at the jazz venue The Bull's Head at Barnes in South West London.
The final line-up featured Chambers, Harrison, Watson, Spoons, Peter Shade and Megs Etherington.
Occasionally "special guests" were allowed onstage, notably Roger Ruskin Spear and Rodney Slater, both from the Bonzo Dog Doo Dah Band.
Members of Bill Posters formed part of Bonzo Bills, who continued to play at The Bull's Head.
