Oh boy, this one really is a cocktail party story - best left to be told over 3 or 4 (or maybe more) gin and tonics.
Catholic boy from Brooklyn who thinks he should be a priest - or maybe in musical theater like his idol (Ethel Merman!) either way - he's gay - meets southern baptist boy who is not sure there are actually any other boys who feels like he does (read, gay). They meet on a cruise ship (um, yes) and move in together for 20 some odd- years.
The good times... and bad times (and there are plenty) ... but they're here... well, at least until the temple they have temporarily taken over on 47th street realizes they aren't getting an audience and hence any profits!
