Whatever the case, we managed to get tickets for “Mama Mia” and spent the next two hours singing our hearts out with Meryl and company. “You can dance, you can jive…”

If you prefer singing along in the comfort of your own home, you’ll have tons of opportunity this week with performances scheduled by Alanis Morissette, Def Leppard, Katy Perry, Sugarland, Alicia Keys, Grizzly Bear, The Duke Spirit, George Michael, Feist, Miley Cyrus and lots more.
