I loved Triple Threat as a child and would love to see it again. As Jimmy mentioned, it was similar to the Jim Lange version, except two teams of three family members competed (adolescent, young adult, and older adult), answering multiple-choice questions based on R&B and hip-hop songs, as well as Black TV shows and movies (in which case, they played the show or movie's theme song). Each generation competed one at a time, and answered three buzz-in questions related to the song.
After a number of rounds, there was a speed round, in which anyone could jump in, and the highest score went to the bonus round, in which the family tried to put cover a 3x3 columned grid, placing song titles under one of three artists' names. If they correctly placed the nine songs in their respective slots, the family won a trip to Disneyworld. At one point, there was a tournament of champions where the families played for a trip to EuroDisney.
With Love B/w the Sexes, my memory's a bit foggy. I *think* a couple went out on a date, and would come back and recall everything that happened. There was also a panel known as the "Peanut Gallery" who offered their input, and in the end, someone (maybe both people) got a $500 prize.
One thing I *do* remember about the show was that one male contestant decided to skip the taping, and the co-hostess told him "Your check will NOT be in the male", to which the audience howled with laughter.
I'd love to see both shows...I remember both having very catchy theme songs, esp. TT.
