Description: George McKelvey (winner of the National Sonny Bono Look-A-Like contest, 1965, 1966 and 1968) sings a lovely scopitone ballad about a guy and his girlfriend who have a fight and he ends up in a fallout shelter and the girlfriend doesn't. It's a protest song... that you can dance to! A retro design; so far as I know there was never a table tent for scopitone S-1046. Scopitones are music films made for a video jukebox in the 1960s. There were over 70 American ones produced and hundreds of European ones, featuring well-known artists of the time. George McKelvey was known more for his comedy than his singing talents.
