"Lip Up Fatty" is a single released by British 2 Tone and ska band Bad Manners in June 1980, which reached No. 15 in the UK Singles Chart. It is one of a number of songs by Bad Manners about 'being fat', (a reference to the round figure of frontman, Buster Bloodvessel). According to Bloodvessel "Lip Up Fatty" was an expression used at his school "to tell people to shut up". Its signature melodic lines were a simple but careful blend of brass instruments and lead harmonica theme, played by Alan Sayag (Winston Bazoomies).
