Lawson Square Infirmary was a 12" extended play released in November 1984 by the Triffids and James Paterson under the collaborative project of the same name.

Lawson Square Infirmary was the result of a one-off recording collaboration between members of the Triffids and Sydney musician James Paterson, of JFK & The Cuban Crisis,[1] who financed the recording and was the Triffids' singer David McComb's occasional song writing collaborator.

The performances were recorded in a couple of takes live to stereo at the Sydney Opera House shortly before the Triffids relocated to London in late August 1984.

Lawson Square Infirmary neatly illustrates Dave's quest for diversity and the prodigious output of songs he had at the timeIn the liner notes to Beautiful Waste and Other Songs: Paterson's history of the recording of Lawson Square Infirmary recounts how the collaboration began when he visited the Triffids' Sydney house for a "typically economical dinner" and played for McComb a riff he had invented that afternoon.

Carshott was a man of coincidence, sharing the name of the lead from a 1937 Australian film, Lovers and Luggers, and the musical skills of the Triffids' Martyn Casey, whom he also strangely resembled.
