I like going out to karaoke with my friends but I am terrible at it.
Perhaps you could gain some practice by playing the Karaoke Revolution series.
What is the Karaoke Revolution series? a game?
Yes, it's a video game on an older generation of consoles such as the Wii, PlayStation 3, and Xbox 360.
Oh cool. Unfortunately the only thing that helps my singing is alcohol.
That's hilarious!  It reminds me of something you'd see on the comedy-drama television series "Glee".
Is Glee still airing? I thought that the show had ended.
Yes, you're right.  The show ended on March 20, 2015, but you can still watch episodes online.
