Jim Richardson is an English jazz bassist and session musician. An original member of pioneering British jazz-rock band, If (1969–1973), he went on to undertake session and studio work. Around 1975–76 he was also a member of Pip Pyle's The Weightwatchers, with Elton Dean and Keith Tippett and leading his own group, Jim Richardson's Pogo Revisited which also featured Alan Barnes. In the late 1970s, his quartet featured Bobby Wellins. In the mid-1980s he re-united with former if band member Dick Morrissey in the jazz-funk band Morrissey–Mullen, before returning to a more straight-ahead jazz approach. Some of the jazz musicians Richardson worked with were Dexter Gordon and Chet Baker.
