I love to karaoke!  I can't sing well, but it sure is fun!
thats the instrumental version of a recording with no vocals so you can sing it right?
I just sing the words on the screen!  Didn't it originate in Japan?
The concept of karaoke has been around almost as long as recordings but not sure if it started in japan
So, karaoke is over 100 years old?
Yes and the difference between karaoke and sing alongs is the lack of lead vocals
