Karaoke Party Night
Turn your garage into a Karaoke paradise. You can rent a machine.. Most now come with a catalog in the thousands of songs. The last time I used one it had 4000 songs. A binder with all songs listed by artist, then the same list organized by song title. Wireless mic's allow for a group to perform at once.
Any adult beverage will get your guests ready to rock. You can't sing, with the group helping out, you will have the time of your life...
A guaranteed good time.
