The Proclaimers and The Farm supported The Housemartins when I saw them in the 80s in Cardiff and I never heard of them. My first impressions of the Proclaimers were not good and they took a lot of flak. The Farm were dreadful.
Best support band were the Cardiacs for It bites - which I still consider one of the most surreal and best gigs I ever saw
