Karaoke crowds are among the most supportive people on earth. Whatever your song choice, whatever your musical talent, if you get up there and sing "Don't Stop Believing" with all your heart, you'll get cheers, applause and possibly a bunch of people singing along with you. At least, that's the vibe whenever we go to The Grapevine, an Old Town Scottsdale hotspot, for karaoke. The two-story space is always busy on the weekends, but the most crowded part of the bar is the karaoke room, where patrons pack in to sing and be serenaded in turn. The karaoke hosts are good about keeping the action moving, and the songbook is extensive — you're sure to find something you want to sing. Just remember to cheer for your fellow crooners when it's your turn to listen.
