Remembering the 80'and 90's : Spotlight Performance

Late, Late, Late, Late, Late, Late. I'm finally posting up the final SPOTLIGHT PERFORMANCE for the semester!! Finals had me occupied and then I forgot, but now I. am. ready.!

MOVING RIGHT ALONG

I'm seeing Christmas and other holiday decorations everywhere but I don't feel like anyone is in the holiday spirit. Maybe it's because I'm older and I don't really care for it too much anymore, but let's see if I can change that. My video will be Christmas themed to hopefully get the mood going.

So this is kind of a Spotlight Performance repeat because I have posted a video of this group before but not of them singing this song. I try not to post videos of the same artist(s) more than once, but I gotta do what I gotta do!

So take that as your first hint, and here are two more:

+ This is an American R&B group.
+ They were originally a quartet, but due to unfortunate circumstances they became a trio.

I think the answer is very very obvious lol. No matter.

LET'S WELCOME BACK TO THE STAGE ......>>>>>>>>

P.S.: The video gets a little fuzzy for a bit at one point.
