Haven't had one of those in years ... sounds like it's time to try it again. As an aside, a few years back I visited the Hawaiian Islands, for some reason SPAM is very popular in that part of the world.
Pork is a major staple there. During the world war, Islanders learned to enjoy the convenience of SPAM. This was covered on a ‘How It’s Made’ program recently, on SPAM! The history of canned meat is indeed interesting, going back to Napoleonic military campaigns.
