Mark Bedford (born Mark William Bedford, 24 August 1961, Islington, North London), nicknamed 'Bedders', is a bass guitarist and founding member, now occasional member, of the band Madness.
Bedford attended William Ellis School in Kentish Town and met members of the North London Invaders when they played a gig there. He was asked along to a band rehearsal and found that the lads could play quite well. Bedford was friends with Gary Dovey who was playing drums with the band, but after a scuffle with sax player Lee Thompson, Dovey left the band. Bedford knew a drummer, and Daniel Woodgate was introduced as the final member of the then six-piece band which became Madness.
Although not the major songwriter in Madness, Bedford co-wrote one of the band's more emotive songs "One Better Day" with Suggs. He was also responsible for co-writing "Not Home Today", "Disappear", "Return of the Los Palmas 7", "Deceives The Eye", "Stepping Into Line" and "Maybe In Another Life". The only song he ever wrote entirely on his own was "Mummy's Boy", which appeared on the band's debut album One Step Beyond....
