This version of "In the Midnight Hour" is by Richard Alden. The opening track is Mike Oldfield's "Taurus 1." I've watched this clip so many times that it's weird hearing these tracks in their entirety.
However, no idea still who did the cringeworthy "Mandy" cover. I guess even Shazam has its pride. :')
I remember an article written about her shortly after her debut with the headline "Yu Sends Me," that also remarked on how attractive she was. Between her and Deborah Norville, channel 5 seemed to specialize in beautiful anchors.
