"A Bus for a Bus on the Bus" is the only 7" single by Cardiac Arrest, who later became Cardiacs.
Until the release of The Special Garage Concerts Vol II, none of the tracks on the 7" had been reproduced anywhere else. The single was supposed to contain four tracks and not three, but the limited space on the 7" format prevented it. The fourth track was to be "Keep Your Dead Mice with You", which was later re-recorded as "Dead Mouse" on the Toy World album. The single is one of the rarest Cardiac Arrest/Cardiacs items.
According to Pugh, Jim Smith broke the E string on his bass during recording. Before recording Cade bought some children's items from a newsagent and brought them to the session. Smith proceeded to give each member a different item and conducted them like an orchestra to make noises on "A Cake for Bertie's Party" during the middle section. During the recording of "Keep Your Dead Mice With You", which was at the end of the session, Smith and Pugh tried to put together a vocal harmony but it was not finished. The songs were mixed at the end of the session and 1000 copies were pressed.
