Chhh as much as I'd be down for Brandy doing it, its just not for her. She's not loose enough and would be tense and nervous. I can see her not even being able to find a song that has the word Baby in it. And when Terrell says 'Sing a song with the word touch'. she would wanna shy away from singing the tougher songs. A chick like Monica would be down to do it, but Brandy would prob cancel on the day of shooting due to vocal unrest.
Now Amber Riley did like a lil' concert special with a small group of ppl and sang the songs live on her EP and that got played on the show. I can see Brandy doing something like that, but a word association to show off her singing, she prob wont. Its gotta be something special for Brandy and I think a performance of her B7 songs would be better plus an interview.
