It's been a decade (!!) since we first saw Gabriella, Troy, Sharpay and the other Wildcats dancing their way through the halls of East High School. To honor the 10th anniversary of High School Musical, the Disney Channel will be airing the musical movie on Wednesday, January 20 — but that's not all. Disney has also brought together the stars of the show -- Vanessa Hudgens, Ashley Tisdale, Lucas Grabeel, Corbin Bleu and Monique Coleman (though sadly, no Zac Efron) -- for the anniversary presentation. Now that's a high school reunion we'd actually like to attend.

To celebrate High School Musical's tenth birthday, we took a look at the original cast then and now. Check out the gallery above for a trip down memory lane, and see how the kids of East High look now.
