Clear your throat and put on your dancing shoes!

If you have a preteen in your house, then no doubt you know all about Disney Channel’s runaway sensation, “High School Musical.” Every time the movie airs it gets blockbuster ratings, and thanks to digital downloads, the soundtrack has dominated the “Billboard” charts for the last two months.

But if you don’t have a preteen (or even teen) running around the house singing “Start of Something New” or “Breaking Free,” then I highly recommend you check this one out yourself because you’ll be singing along in no time.

At 8 p.m. tonight (Friday), Disney Channel will air a special dance-along version of “High School Musical,” with cast members teaching you some of the dance steps (The movie is beautifully choreographed by Kenny Ortega of “Dirty Dancing” fame.). At 10 p.m., the movie will air again, but this time it’s a sing-along version.

If you miss this chance, don’t worry. “Musical” hits DVD May 23rd…
