Good morning, Pop Watchers! Okay, I know, it may not actually be morning when you’re reading this, but I still can’t get that catchy ditty “Good Morning Baltimore” from Hairspray out of my head. (Damn you, brilliant songwriting of Marc Shaiman and Scott Wittman!) Lucky for me, New Line has arranged a bunch of special Hairspray sing-a-longs this weekend: Selected theaters across the nation (though, ironically, none in Baltimore) will show the hit musical and encourage audience members to belt out the film’s tunes with their fellow Zac Efron wannabes. Just like those Sing-A-Long Sound of Music fiestas that have been so popular. Sounds like fun, huh? Are you looking forward to going out and unleashing your inner Nikki Blonsky? Well, hey, friends, if you happen to catch the event near where you live, do us a favor and report back. If, that is, you’re not too hoarse.
