In August 1987 EUROPE went to Japan to play at the telethon 24 Hour Television. From what I can tell, they performed twice:
"The Final Countdown" and "Love Chaser"
"The Final Countdown" and "Rock the Night"
These performances are notable for the fact that this is one of very few times that Joey hits all the high notes in "The Final Countdown". I've seen videos before, but they've been of pretty low quality. Today I found them in very good quality, so here they are! Enjoy!
EDIT: The old YouTube links were broken, so I've reuploaded the videos to my channel.
