Karaoke anyone?

In my past working life I was a motivator and sales trainer, these days I do some English teaching, but I'm wanting to get back to motivational training and karaoke is a fantastic way to break the ice between people, especially if some idiot like me takes the first shot at the microphone.

Where I live karaoke CD's aren't generally available, and on top of that, a lot of people here aren't really familiar with the sorts of songs that I grew up with, many of them are big fans of Spanish flamenco singers who are unknown outside of Spain.

Some downloadable software that automatically removes lead vocals from a stereo mp3 is just what is needed, and in my little classes it goes down a treat, I remove the Spanish vocals, give my students the English lyrics, and let them sing to their heart's content. Of course I only do this for social evenings but it's a really cheap way to entertain people and takes virtually no time to prepare.
