The Graham Bond Organisation (GBO) were a British jazz/rhythm and blues group of the mid-1960s consisting of Graham Bond (vocals, keyboards, alto-saxophone), Jack Bruce (bass), Ginger Baker (drums), Dick Heckstall-Smith (tenor/soprano saxophone) and John McLaughlin (guitar). They recorded several albums and further recordings were issued when the group's members achieved fame in progressive rock and jazz fusion. The spelling of the band's original name varied between releases, often depending on the intended audience. The British English spelled as "Organisation" or "ORGANisation" (Bond's original plan), while in some other countries outside the UK spelled "Organization".
