Weird-ish Video, can't think of the lyrics

OK, I know the song is by two girls, and that's the title of the band ___ and ___ (their names). OK, so in the video the two girls are on stage, and there are a bunch of people in the audience in all white body suits and all black body suits. And maybe all red as well, if I remember correctly. Anyway...that's all I remember. Any help would be AWESOME.

Trying to narrow this down, is the duet called Aly & AJ?

how old is this group?

if they're from the 80s my guess is mel and kim lol

I know it's not either of those. I think one or both of the names started with a T. They were older, maybe late 20's, early 30's. They were both brunette, they looked like sisters...I don't know if that helps.

Maybe Teagan and Sara?? I have no idea how I remembered that. All those issues of Blender...

That's it! Thanks so much, EVERYBODY.
