It wasn’t super-common but also by no means unheard-of, most often involving acts who were more or less 60s / beat inspired - off the top of my head you can expect to hear organ on records by the likes of the Prisoners, Makin’ Time, TVPs, Jasmine Minks, bit later on the Sea Urchins, Inspiral Carpets.
