DESCRIPTION:
"LaRCS" stands for "Live and Record Combined Stereo", which means that on the left you can hear a live performance, while on the right the clip version.
Regarding the current video, you can see Brenda Lee's classic song "Here Comes That Feeling": on the right side the studio version by Brenda, while on the left side a live presentation from 2007 by Roxanne Wilde (Roxy) together with his famous father (Marty Wilde) and his band during his 50 years anniversary concert (London). As you can see, Roxy is not just a pretty face (and a very nice person), but she has the music in her genes. She's a very good live performer. (Her elder sister, Kim was also one of the biggest stars in pop music!) In the recent years you can see/hear Roxy mostly singing together with Lucy supporting Kylie Minogue.
Note: I had to apply some tempo adjustment on Brenda's version.
