I agree with the first comment. Night Club Two Steps would be the easiest for you and your husband to learn and practice. It's simple and fun to dance without paying too much attention with your body movement unlike the wedding dances like Rumba, Waltz and Foxtrot.
Jive would be too fast for beginners and hustle steps would be complicated for beginners. Night Club Two Steps can be danced to slow music or a little faster music. In my personal experience, though, Lady in Red and I always love you are The best musics for Night Club Two Steps.
GOOD LUCK!
