Remember how pop star Tiffany used to do mall tours back in the ’80s? Ah, good times at the Orange Julius. The songbirds from TV show Glee are continuing that fine tradition with store appearances in New York and L.A. next week to promote the album Glee: The Music, Volume 1. They’ll be signing at Borders Columbus Circle on November 3, with Lea Michele, Cory Monteith and Dianna Agron (Rachel, Finn and Quinn), among others, in attendance. They won’t be actually singing (boo), but that doesn’t mean you can’t lead your own sing-along to “Sweet Caroline” in honor of the kick-ass Mark Salling (Puck). (Besides, rumors point to a spring tour for the McKinley High Glee Club. Score!)
